Chapter 1. The Guided Tour

If you’d never seen all the videos and photos of the iPhone, and you found it lying on someone’s desk, you might not guess it was a phone (let alone an iPod/Web browser/alarm clock/stopwatch/voice recorder/musical instrument/compass). You can’t see any antenna, mouthpiece, or earpiece—and goodness knows there are no number keys for dialing.

It’s all there, though, hidden inside this sleek glass-and-metal slab.

For the rest of this book, and for the rest of your life with the iPhone, you’ll be expected to know what’s meant by, for example, “the Home button” and “the Sleep switch.” A guided tour, therefore, is in order. Keep hands and feet inside the tram at all times.

Sleep Switch (On/Off)

On the top-right edge of the iPhone, you’ll find a metal button shaped like a dash. This, ladies and gents, is the Sleep switch.

image with no caption

It has several functions:

  • Sleep/Wake. Tapping it once puts the iPhone to sleep—into Standby mode, ready for incoming calls but consuming very little power. Tapping it again turns on the screen so it’s ready for action.

  • On/Off. The same switch can also turn the iPhone off completely so it consumes no power at all; incoming calls get dumped into voicemail. You might turn the iPhone off whenever you’re not going to use it for a few days.

    To turn the iPhone off, press the Sleep switch for 3 seconds. The screen changes to say slide to power off. Confirm your decision by placing a fingertip on the right-pointing red arrow and sliding to the right. The device shuts off completely.

    Tip

    If you change your mind about turning the iPhone off, tap the Cancel button, or do nothing; after a moment, the iPhone backs out of the slide to power off screen automatically.

    image with no caption

    To turn the iPhone back on, press the switch again for 1 second. The chromelike Apple logo appears as the phone boots up.

  • Answer call/Dump to voicemail. When a call comes in, you can tap the Sleep button once to silence the ringing or vibrating. After four rings, the call goes to your voicemail.

    You can also tap it twice to dump the call to voicemail immediately. (Of course, because they didn’t hear four rings, iPhone veterans will know you’ve blown them off. Bruised egos may result. Welcome to the world of iPhone etiquette.)

  • Force restart. The Sleep switch has one more function. If your iPhone is frozen, and no buttons work, and you can’t even turn the thing off, this button is also involved in force-restarting the whole machine. Steps for this last-ditch procedure are on Reset: Six Degrees of Desperation.

Locked Mode

When you don’t touch the screen for 1 minute (or another interval you choose), or when you put the iPhone to sleep, the phone locks itself. When it’s locked, the screen is dark and doesn’t respond to touch. If you’re on a call, the call continues; if music is playing, it keeps going; if you’re recording audio, the recording proceeds.

But when the phone is locked, you don’t have to worry about accidental button pushes. You wouldn’t want to discover that your iPhone has been calling people or taking photos from the depths of your pocket or purse. Nor would you want it to dial a random number from your back pocket, a phenomenon that’s earned the unfortunate name butt dialing.

The Lock Screen

To wake the phone when it’s locked, press either the Sleep switch or the Home button just below the screen.

That gesture alone doesn’t fire up the full iPhone world, though. Instead, it presents the Lock screen shown here.

From here, slide your finger to the right across the gray arrow, as indicated by the animation, to unlock the phone, wake it up, and start using it.

Note

The iPhone can demand a password each time it wakes up, if you like. See General. On the other hand, you can adjust how quickly the phone locks itself, or make it stop locking itself altogether; see General.

image with no caption

These days, the Lock screen is more than just a big Do Not Disturb sign. It’s a veritable bulletin board for up-to-date information about your life—information you can scan without unlocking the phone at all.

For starters, you can use the iPhone as a watch—millions of people do. Just tap the Sleep switch to consult the Lock screen’s time and date display, and then shove the phone right back into your pocket. The iPhone relocks after a few seconds.

If you’re driving, using the Maps app to guide you, the Lock screen shows the standard navigation screen (Navigation Mode). Handy, really—the less fumbling you have to do while driving, the safer you are.

Better yet, the Lock screen is a handy status screen. Here you see a record of everything that happened while you weren’t paying attention. It’s a list of missed calls, text messages received, notifications from your apps, and other essential information.

Now, each of these notices has come from a different app (software program). To call somebody back, for example, you’d want to open the Phone app; to reply to a text message, you’d want the Messages app, and so on.

Here, then, is a handy shortcut: You can dive directly into the relevant app by swiping your finger across the notification itself, like this:

image with no caption

Adopting that shortcut saves you the trouble of unlocking the phone, fumbling through your Home screens until you find the app you want, and tapping it to open it.

Tip

On the other hand, if you’d rather not have all these details show up on the Lock screen, you can turn them off. (Privacy is the main reason you might want to do so—remember that the bad guys don’t need a password to view your Lock screen. They just have to tap the Sleep switch or the Home button.)

You can hide these items from your Lock screen on an app-by-app basis. For example, you might want missed calls to show up here but not missed text messages. To set this up, choose Settings→Notifications. Tap the app in question; scroll to the bottom, and then turn off View in Lock Screen.

Home Button

Here it is: the one and only button on the front of this phone. Push it to summon the Home screen, which is your gateway to everything the iPhone can do. (You can read more about the Home screen at the end of this chapter.)

image with no caption

Having a Home button is a wonderful thing. It means you can never get lost. No matter how deeply you burrow into the iPhone software, no matter how far off track you find yourself, one push of the Home button takes you back to the beginning.

It sounds simple, but remember that the iPhone doesn’t have an actual Back button or an End button. The Home button is the only way out of some screens.

As time goes on, Apple keeps saddling the Home button with more and more functions. It’s become Apple’s only way to provide shortcuts for common features; that’s what you get when you design a phone that only has one button. In iPhone Land, you can press the Home button one, two, or three times for different functions—or even hold it down. Here’s the rundown.

Quick Press: Wake Up

Pressing the Home button once wakes the phone if it’s in locked mode. That’s sometimes easier than finding the Sleep switch on the top edge. It gives you a quick glance at your missed calls and texts—or the time and date.

Long Press: Siri (or Voice Control)

If you hold down the Home button for about 3 seconds, you make the phone ready for voice control.

If you have an iPhone 3GS or 4, you can use voice control to dial by speaking a name or a number, or use it to control music playback. If you have an iPhone 4S or 5, you can do a thousand times more: You can command Siri, your virtual voice-controlled assistant. Details are in Chapter 4.

Two Quick Presses: Task Switcher

If, once the phone is awake, you press the Home button twice quickly, the screen dims, and the current image on it slides upward—to reveal the task switcher strip at the bottom. This feature is the key to the iPhone’s multitasking feature.

What you see here are icons of the four programs you’ve used most recently. Each time you swipe your finger to the left, you bring more icons into view, representing programs you opened less and less recently.

image with no caption

The point is that with a single tap, you can jump right back into a program you had open, without waiting for it to start up, show its welcome screen, and so on—and without having to scroll through 11 Home screens trying to find the icon of a favorite app.

In short, the task switcher gives you a way to jump directly to another app, without a layover at the Home screen first.

This task switcher is the only visible element of the iPhone’s multitasking feature, which is described in delicious detail on Multitasking. Once you get used to it, that double-press of the Home button will become second nature—and your first choice for jumping among apps.

Two Quick Presses, Part 2: The Widget Bar

Most of the time, you’ll do the two-presses thing to open the task switcher so you can, well, switch tasks. But there are hidden gems awaiting.

If you summon the task switcher and then drag your finger to the right, the task switcher reveals a set of four hidden controls. These go by the name of widgets, meaning that they’re not quite as full blown as actual apps, but they still get their own icons. Here’s what they do, from left to right:

  • Rotation lock. When you tap this button, the screen no longer rotates when you turn the phone 90 degrees. The idea is that sometimes, like when you’re reading an ebook on your side in bed, you don’t want the screen picture to turn; you want it to stay upright relative to your eyes, even though you’re lying down. (A little icon appears at the top of the screen to remind you why the usual rotating isn’t happening.)

    The whole thing isn’t quite as earth-shattering as it sounds—first, because it locks the image in only one way: upright, in portrait orientation. You can’t make it lock into widescreen mode. Furthermore, there aren’t that many apps that rotate with the phone to begin with. But when that day comes when you want to read in bed on your side with your head on the pillow, your iPhone will be ready. (Tap the button a second time to turn rotating back on.)

  • , , . These controls govern playback in whatever program is playing music in the background. They’re always two Home-button presses away, no matter what program you’re in. You can skip a horrible song quickly and efficiently without having to interrupt what you’re doing.

    image with no caption
  • Music-app button. The app icon here represents your iPhone’s iPod app, or the Pandora Internet radio app, or the Spotify app, or whatever program is playing music in the background at the moment. Once again, the idea is to give you a quick shortcut when you want to switch albums, songs, or podcasts, so you don’t have to meander back to the Home screen.

  • Volume slider and AirPlay control. New in iOS 6: If you swipe again to the right from the music-playback controls, you reveal a volume slider and a button that lets you switch playback to a wireless speaker or Apple TV, courtesy of AirPlay (AirPlay), as shown above at right. The point, once again, is to give you quick access without having to unlock the phone or interrupt what you’re doing.

Three Presses: VoiceOver, Zoom, White on Black…

In Settings→General→Accessibility, you can set up a triple-press of the Home button to turn one of several accessibility features on or off: VoiceOver (the phone speaks whatever you touch), Invert Colors (white-on-black type, which is sometimes easier to see), Zoom (magnifies the screen), AssistiveTouch (help for people who have trouble with physical switches) or Guided Access (aka kiosk mode).

All of these features are described beginning on Kiosk Mode, Large Type & Accessibility.

Tip

The Home button is also part of the force quit sequence—a good troubleshooting technique when a particular program seems to be acting up. See Reset: Six Degrees of Desperation.

Silencer Switch, Volume Keys

Praise be to the gods of technology—this phone has a silencer switch! This tiny flipper, on the left edge at the top, means that no ringer or alert sound will humiliate you in a meeting, at a movie, or in church. To turn off the ringer, push the flipper toward the back of the phone (see the photo on What’s New in iOS 6).

Note

Even when silenced, the iPhone still makes noise in certain circumstances: when an alarm goes off; when you’re playing iPod music; when you’re using Find My iPhone (Photo Stream); when you’re using VoiceOver (VoiceOver); or, sometimes, when a game is playing. Also, the phone still vibrates when the silencer is engaged, although you can turn this feature off; see Sounds.

No menus, no holding down keys, just instant silence. All cellphones should have this feature.

With practice, you can learn to tell if the ringer is on while the iPhone is still in your pocket. That’s because when the ringer is on, the switch falls in a straight line with the volume keys. By swiping your thumb across these controls, you can feel whether the silencer switch is lined up or tilted away.

Below the silencer, still on the left edge, are the volume controls—separate metal + and – buttons. The volume controls work in five different ways:

  • On a call, these buttons adjust the speaker or earbud volume.

  • When you’re listening to music, they adjust the playback volume—even when the phone is locked and dark.

  • When you’re taking a picture, the middle one (volume up) serves as a shutter button or a camcorder start/stop button.

  • At all other times, they adjust the volume of sound effects like the ringer and alarms.

  • When a call comes in, they silence the ringing or vibrating.

In each case, if the screen is on, a corresponding volume graphic appears on the screen to show you where you are on the volume scale.

Screen

The touchscreen is your mouse, keyboard, dialing pad, and notepad. You might expect it to get fingerprinty and streaky.

But one of the best unsung features of the modern iPhone is its oleophobic screen. That may sound like an irrational fear of yodeling, but it’s actually a coating that repels grease. You’ll be amazed at how easily a single light wipe on your clothes restores the screen to its right-out-of-the-box crystal sheen.

You can also use the screen as a mirror when the iPhone is off.

The iPhone’s Retina screen has crazy high resolution (the number of tiny pixels per inch)—the highest resolution of any phone on the market. It’s really, really sharp, as you’ll discover when you try to read text or make out the details of a map or a photo. The iPhone 4 and 4S pack in 960 x 640 pixels; the iPhone 5, with its extra half-inch of screen, manages 1136 x 640 pixels.

The front of the iPhone is made of Gorilla Glass, a special glass formulation made by Corning. It’s unbelievably resistant to scratching. (That doesn’t mean it can’t crack; you can still shatter it if you drop it just the right way.) The back of the 4 and 4S are Gorilla Glass, too.

Note

This is how Corning’s Web site says this glass is made: “The glass is placed in a hot bath of molten salt at a temperature of approximately 400°C. Smaller sodium ions leave the glass, and larger potassium ions from the salt bath replace them. These larger ions take up more room and are pressed together when the glass cools, producing a layer of compressive stress on the surface of the glass. Gorilla Glass’s special composition enables the potassium ions to diffuse far into the surface, creating high compressive stress deep into the glass. This layer of compression creates a surface that is more resistant to damage from everyday use.”

But you probably guessed as much.

If you’re nervous about protecting your iPhone, you can always get a case for it (or a “bumper” for the iPhone 4 or 4S—a silicone band that wraps around the metal edges). But if you’re worried about scratching the glass, you’re probably worrying too much. Even many Apple employees carry the iPhone in their pockets without carrying cases.

Radio signals can’t pass through metal. That’s why there are strips of glass on the back of the iPhone 5—right where the antennas are—and why the 4 and 4S have all-glass backs.

And there are a lot of radio signals in this phone. All told, there are 15 different radio transceivers inside: four for the standard GSM frequencies; four for GSM’s 3G frequencies; three for CDMA frequencies; and one each for WiFi, Bluetooth, American GPS, and Russian GPS.

Screen Icons

Here’s a roundup of the icons you may see in the status bar at the top of the iPhone screen, from left to right:

  • Cell signal. As on any cellphone, the number of bars indicates the strength of your cell signal, and thus the quality of your call audio and the likelihood of losing the connection. If there are zero bars, then the dreaded words “No service” appear here.

  • Network name and type. These days, different parts of the country—and even different parts of your street—are blanketed by cellular Internet signals of different speeds, types, and ages. Your status bar always shows you the kind of signal it has right now.

    From slowest to fastest: or means your iPhone is connected to your carrier’s slowest, oldest Internet system. You might be able to check email, but you’ll lose your mind waiting for a Web page to load.

    If you see the logo, though, you’re in a city where your cell company has installed a 3G network—meaning fairly decent Internet speed. A logo is better yet; you have speed in between 3G and LTE.

    And if you see up there—well, then, get psyched. You have an iPhone 5 and you’re in one of the lucky cities that has a 4G LTE cellular network. And that means insanely fast Internet (maybe even faster than you have at home), fast Web browsing, fast app downloading—just fast.

  • Airplane mode. If you see the airplane instead of signal and WiFi bars, then the iPhone is in Airplane mode (Airplane Mode and WiFi Off Mode).

  • Do Not Disturb. When the phone is in Do Not Disturb mode, nothing can make it ring, buzz, or light up except calls from the most important people. Details on Remind Me Later.

    image with no caption
  • WiFi signal. When you’re connected to a wireless Internet hotspot, this indicator appears. The more “sound waves,” the stronger the signal.

  • 9:50 AM. When the iPhone is unlocked, a digital clock appears on the status bar.

  • Play indicator. The iPhone is playing music. Before you respond, “Well, duh!” keep in mind that you may not be able to hear the music playing. For example, maybe the earbuds are plugged into the iPhone but aren’t in your ears. So this icon is actually a handy reminder that you’re running your battery down unnecessarily.

  • Alarm. You’ve got an alarm set. This reminder, too, can be valuable, especially when you intend to sleep late and don’t want an alarm to go off. See Alarm for setting (and turning off) alarms.

  • Bluetooth. The iPhone is connected wirelessly to a Bluetooth earpiece, speaker, or car system; see Bluetooth Car Systems. (If this symbol is gray, then it means Bluetooth is turned on but not connected to any other gear.)

  • TTY symbol. You’ve turned on Teletype mode, meaning that the iPhone can communicate with a Teletype machine. (That’s a special machine that lets deaf people make phone calls by typing and reading text. It hooks up to the iPhone with a special cable that Apple sells from its Web site.)

  • Call forwarding. You’ve told your iPhone to auto-forward any incoming calls to a different number (Call Forwarding). This icon is awfully handy—it explains at a glance why your iPhone never seems to get calls anymore.

  • VPN. You corporate stud, you! You’ve managed to connect to your corporate network over a secure Internet connection, probably with the assistance of a systems administrator—or by consulting Virtual Private Networking (VPN).

  • Syncing. The iPhone is currently syncing with some Internet service—iCloud, for example (Chapter 14).

  • Tethering. You’ve turned on the Personal Hot Spot (Personal Hotspot (Tethering)).

  • Battery meter. When the iPhone is charging, the lightning bolt appears. Otherwise, the battery logo “empties out” from right to left to indicate how much charge remains. (You can even add a “% full” indicator to this gauge; see General.)

  • Navigation active. You’re running a GPS navigation program in the background (yay, multitasking!). Why is a special icon necessary? Because those GPS apps slurp down battery power like a thirsty golden retriever. Apple wants to make sure you don’t forget you’re running it.

  • Rotation lock. This icon reminds you that you’ve deliberately turned off the screen-rotation feature, where the screen image turns 90 degrees when you rotate the phone. Why would you want to? And how do you turn the rotation lock on or off? See Two Quick Presses, Part 2: The Widget Bar.

Tip

In iOS 6, the status bar’s color changes from app to app. In standard apps (those with rounded top corners), it’s still black. But in apps with square top corners, the status bar’s color matches, of all things, the very bottom pixel row of the app’s header bar. Think of it as iOS’s version of Skittles.

Cameras and Flash

At the top of the phone, above the screen, there’s a horizontal slot. That’s the earpiece. Just above it (iPhone 5) or beside it (iPhone 4 or 4S), the tiny round pinhole is the front-facing camera. It’s a little bit more visible on the white iPhone than on the black one.

Its primary purpose is to let you conduct video chats using the FaceTime feature, but it’s also handy for taking self-portraits or just checking to see if you have spinach in your teeth.

Just keep in mind that it’s not nearly as good a camera as the one on the back. The front camera has no flash, isn’t as good in low light, and takes much lower-resolution shots (1.2 megapixels on the iPhone 5, only 0.3 megapixels on earlier models).

image with no caption

The camera on the back of the iPhone, meanwhile, takes very good photos indeed—8 megapixels on the iPhone 4S and 5.

On the iPhone 4 and later, a tiny LED lamp appears next to this lens. It’s the flash for the camera, the video light when you’re shooting movies, and a darned good flashlight for reading restaurant menus and theater programs in low light. (A free app like LED Light makes it quick and easy to turn the light on and off.)

On the iPhone 5, the tiny pinhole between the flash and the lens is a microphone. It’s used for recording clearer sound with video, for better noise cancellation on phone calls, and better directional sound pickup.

There’s more on the iPhone’s cameras in Chapter 7.

Sensors

Behind the glass, above or beside the earpiece, are two sensors. (On the black iPhones, they’re camouflaged; you can’t see them except with a bright flashlight.) First, there’s an ambient-light sensor that brightens the display when you’re in sunlight and dims it in darker places. You can also adjust the brightness manually; see Brightness & Wallpaper.

Second, there’s a proximity sensor. When something (like your head) is close to the sensor when you’re using the phone functions, it shuts off the screen illumination and touch sensitivity. Try it out with your hand (it works only in the Phone app). You save power and avoid dialing with your cheekbone when you’re on a call.

SIM Card Slot

On the right edge of the iPhone 4S and 5, there’s a tiny pinhole next to what looks like a very thin slot cover. (It’s also on the right side of the AT&T iPhone 4 or the top of the iPhone 3GS.) If you push an unfolded paper clip straight into the hole, the SIM card tray pops out.

So what’s a SIM card?

image with no caption

It turns out that there are two major cellphone network types: CDMA, used by Verizon and Sprint, and GSM, used by AT&T, T-Mobile, and most other countries around the world.

Every GSM phone stores your phone account info—things like your phone number and calling-plan details—on a tiny memory card known as a SIM (subscriber identity module) card. On some phones, though not on the iPhone, it even stores your address book.

What’s cool is that, by removing the card and putting it into another GSM phone, you transplant a GSM phone’s brain. The other phone now knows your number and account details, which can be handy when your iPhone goes in for repair or battery replacement.

iPhone 5: The World Phone

AT&T is a GSM network, so AT&T iPhones have always had SIM cards. But intriguingly enough, every iPhone 4S and iPhone 5 has a SIM card, too—even the Verizon and Sprint models. That’s odd, because most CDMA cellphones don’t have SIM cards.

That’s because these iPhones contain antennas for both GSM and CDMA. It’s the same phone, no matter which cell company you buy it from. Only the activation process teaches it which phone company it “belongs” to.

Even then, however, you can still use any company’s phone in any country. (That’s why the latest iPhones are said to be “world phones.”) When you use the Verizon or Sprint iPhone in the United States, it uses only the CDMA antenna. But if you travel to Europe or another GSM part of the world, you can still use your Verizon or Sprint phone; it just hooks into that country’s GSM network.

If you decide to try that, you have two ways to go. First, you can contact your phone carrier and ask to have international roaming turned on. You’ll keep your same phone number overseas, but you’ll pay through the nose for calls and, especially, Internet use.

Second, you can rent a temporary SIM card when you get to the destination country. That’s a less expensive route, but it means you’ll have a different phone number while you’re there.

image with no caption

The original iPhones used a standard SIM card. The iPhone 4S and the AT&T iPhone 4 require a smaller type known as a micro SIM card. And for the iPhone 5, Apple has developed even newer, tinier cards called nano SIMs. (You can see all three cards at left.)

At this rate, you won’t even be able to see the iPhone 7’s SIM card without an electron microscope.

Apple thinks SIM cards are geeky and intimidating and that they should be invisible. That’s why, unlike most GSM phones, your iPhone came with the card preinstalled and ready to go. Most people will never have any reason to open this tray, unless they just want to see what a SIM card looks like.

If you were curious enough to open it up, you can close the tray simply by pushing it back into the phone until it clicks.

Note

Except for this one example—inserting a card from another country for international use—you can’t swap any other company’s SIM card into the iPhone. For example, you can’t make it a T-Mobile phone by inserting a T-Mobile SIM card. In other words, the iPhone is still not an “unlocked” GSM phone (at least, not officially; there are some unauthorized ways).

And speaking of footnotes: the iPhone 5 may be an LTE phone, but it doesn’t work on the LTE networks of all other countries. Ask you carrier which countries your model works with.

Headphone Jack

On the top edge of the iPhone 3GS, 4, and 4S, or the bottom edge of the iPhone 5, you can see the miniplug where you plug in the white earbuds that came with it—or any other earbuds or headphones.

This little hole is more than an ordinary 3.5-millimeter audio jack, however. It contains a secret fourth pin that conducts sound into the phone from the microphone on the earbuds’ cord. Now you, too, can be one of those executives who walk down the street barking orders, apparently to nobody. The iPhone can stay in your pocket as you walk or drive. You hear the other person through your earbuds, and the mike on the cord picks up your voice.

Note

Next to the headphone jack, inside the pinhole (iPhone 4/4S) or the perforated grille (iPhone 5), a tiny second microphone lurks. It’s the key to the iPhone’s noise-cancellation feature. It listens to the sound of the world around you and pumps in the opposite sound waves to cancel out all that ambient noise. It doesn’t do anything for you—the noise cancellation affects only what the other guy on the phone hears.

That’s why, on the iPhone 5, there’s also a third microphone at the top back (between the camera and flash); it’s designed to supply noise cancellation for you so that the other guy sounds better to you when you’re in a noisy place.

image with no caption

Microphone, Speakerphone

On the bottom edge of the iPhone, Apple has parked two important audio components: the speakerphone speaker and the microphone.

Tip

The speakerphone isn’t super loud, because it’s aimed straight out of the iPhone’s edge, away from you. But if you cup your hand around the bottom edge, you can redirect the sound toward your face, for an immediate boost in volume and quality.

The Charge/Sync Connector

Directly below the Home button, on the bottom edge of the phone, you’ll find the connector that charges and syncs the iPhone with your computer.

The Lightning Connector

For nearly 10 years, the charge/sync connector was identical on every iPhone, iPod, and iPad. It was the standard 30-pin connector that’s now found in many alarm clocks, hotel-room bedside tables, car dashboards, speaker docks, external batteries, and other accessories.

image with no caption

But on the iPhone 5, Apple replaced that inch-wide connector with a new, far smaller one it calls Lightning.

The Lightning connector is a great design: It clicks nicely into place (you can even dangle the iPhone from it), yet you can yank it right out. You can insert the Lightning into the phone either way—there’s no “right-side up” anymore. It’s much sturdier than the old connector. And it’s tiny, which is Apple’s primary goal—only 0.3 inches wide (the old one was almost 0.9 inches wide).

Unfortunately, as a result, the iPhone 5 doesn’t fit any existing charging cables, docks, chargers, car adapters, hotel-room alarm clocks, speakers, or accessories.

The makers of those accessories will happily sell you new models that have Lightning connectors. Or you can buy an adapter from Apple:

  • Additional USB charging cables, like the one that came with your iPhone 5, cost $20.

  • A white adapter plug costs $30. It connects the iPhone 5 to any accessory that was built for the old 30-pin connector.

  • If the iPhone 5 doesn’t quite fit the older accessory, sometimes the solution is the $40 adapter plug with an eight-inch cable “tail.”)

Even with the adapter, the Lightning connector doesn’t work with every older accessory, and it doesn’t offer all the same features. For example, it can’t send video out to your TV; for that, you need Apple’s Lightning-to-HDMI or Lightning-to-VGA cable.)

In time, as the Lightning connectors come on all new iPhones, iPods, and iPads, a new ecosystem of accessories will arise. We’ll arrive at a new era of standardization—until Apple changes jacks again in another 10 years.

Antenna Band

That metal band around the edge is one of the most famous features of recent iPhones. This band (aluminum on the iPhone 5, stainless steel on the 4 and 4S) is the primary structural component of the phone—everything else is attached to it.

image with no caption

But this band is also part of the iPhone’s antenna.

It was also part of the controversy that erupted after the iPhone 4 debuted in the summer of 2010. Remember that? If you held the iPhone 4 so that the lower-left corner was pressed into your palm, the signal strength sometimes dropped. Even more intriguing: Putting the phone in a case or in one of Apple’s silicone “bumpers” eliminated the problem.

Eventually, the hysteria died down. The problem doesn’t occur at all on the 4S or the 5; you can hold these phones any way you like.

In the Box

Inside the minimalist box, you get the iPhone and these items:

  • The earbuds. Apple shipped 600 million of the iconic white earbuds that, for years, have announced to the world, “I’m an iPhone!” or “I’m an iPod!” But for the iPhone 5, Apple updated them. Now you get what Apple calls EarPods. They stay put in more people’s ears, and they sound better, although their bulbous shape may get uncomfortable in smaller ears. As before, a volume control/clicker is right on the cord, so you can answer calls and pause the music without taking the phone out of your pocket.

    image with no caption
  • The USB charging/syncing cable. When you connect your iPhone to your computer using this white USB cable, it simultaneously syncs and charges. See Chapter 13.

  • The AC adapter. When you’re traveling without a computer, you can plug the dock’s USB cable into the included two-prong outlet adapter, so you can charge the iPhone directly from a wall socket.

  • Finger Tips. Cute name for a cute foldout leaflet of iPhone basics.

You don’t need a copy of the iTunes software, or even a computer, to use the iPhone anymore—but it makes loading up the phone a lot easier, as described in Chapter 13.

If you don’t have iTunes on your computer, then you can download it from www.apple.com/itunes.

Seven Basic Finger Techniques

The iPhone isn’t quite like any machine that came before it, and operating it isn’t quite like using any other machine. You do everything on the touchscreen instead of with physical buttons. Here’s what you need to know.

Tap

You’ll do a lot of tapping on the iPhone’s onscreen buttons. They’re usually nice and big, giving your fleshy fingertip a fat target.

You can’t use a fingernail or a pen tip; only skin contact works. (OK, you can also buy an iPhone stylus. But a fingertip is cheaper and much harder to misplace.)

Swipe

In some situations, you’ll be asked to confirm an action by swiping your finger across the screen. That’s how you unlock the phone after it’s been in your pocket, for example. It’s ingenious, really; you may bump the touch screen when you reach into your pocket for something, but it’s extremely unlikely that your knuckles will randomly swipe it in just the right way.

You also have to swipe to confirm that you want to turn off the iPhone, to answer a call on a locked iPhone, or to shut off an alarm. Swiping like this is also a great shortcut for deleting an email or a text message.

Drag

When you’re zoomed into a map, Web page, email, or photo, you can scroll around just by sliding your finger across the glass in any direction—like a flick (described below), but slower and more controlled. It’s a huge improvement over scroll bars, especially when you want to scroll diagonally.

Flick

A flick is a faster, less-controlled slide. You flick vertically to scroll lists on the iPhone. You’ll discover—usually with some expletive like “Whoa!” or “Jeez!”—that scrolling a list in this way is a blast. The faster your flick, the faster the list spins downward or upward. But lists have a real-world sort of momentum; they slow down after a second or two, so you can see where you wound up.

At any point during the scrolling of a list, you can flick again (if you didn’t go far enough) or tap to stop the scrolling (if you see the item you want to choose).

Pinch and Spread

In programs like Photos, Mail, Web, and Maps, you can zoom in on a photo, message, Web page, or map by spreading.

That’s when you place two fingers (usually thumb and forefinger) on the glass and spread them. The image magically grows, as though it’s printed on a sheet of rubber.

Note

The English language has failed Apple here. Moving your thumb and forefinger closer together has a perfect verb: pinching. But there’s no word to describe moving them the opposite direction.

Apple uses the oxymoronic expression pinch out to describe that move (along with the redundant-sounding pinch in). In this book, the opposite of “pinching” is “spreading.”

Once you’ve zoomed in like this, you can zoom out again by putting two fingers on the glass and pinching them together.

Double-Tap

Double-tapping is actually pretty rare on the iPhone, at least among the programs supplied by Apple. It’s not like the Mac or Windows, where double-clicking the mouse always means “open.” Because the iPhone’s operating system is far more limited, you open something with one tap.

A double-tap, therefore, is reserved for two functions:

  • In the Safari (Web browser), Photos, and Maps programs, double-tapping zooms in on whatever you tap, magnifying it. (Double-tapping means “restore to original size” after you’ve zoomed in.) Double-tapping also zooms into some email messages—the ones formatted like Web pages—as well as PDF files, Microsoft Office files, and others.

  • When you’re watching a video (or recording one), double-tapping switches the aspect ratio (video screen shape).

Two-Finger Tap

This weird little gesture crops up in only one place: Maps. It means “zoom out.” To perform it, tap once on the screen—with two fingers.

Charging the iPhone

The iPhone has a built-in, rechargeable battery that fills up a substantial chunk of its interior. How long one charge can drive your iPhone depends on what you’re doing—music playback saps the battery the least, Internet and video sap it the most. But one thing is for sure: Sooner or later, you’ll have to recharge the iPhone. For most people, that’s every night or every other night.

You recharge the iPhone by connecting the white USB cable that came with it. You can plug the far end into either of two places to supply power:

  • Your computer’s USB jack. In general, the iPhone charges even if your computer is asleep. (If it’s a laptop that itself is not plugged in, though, the phone charges only if the laptop is awake. Otherwise, you’d come home to a depleted laptop.)

  • The AC adapter. The little white two-prong cube that came with the iPhone connects to the end of the cradle’s USB cable.

Unless the charge is really low, you can use the iPhone while it’s charging. If the iPhone is unlocked, then the battery icon in the upper-right corner displays a lightning bolt to let you know that it’s charging. If it’s locked, pressing the Home button shows you a battery gauge big enough to see from space.

Note

The iPhone’s battery isn’t user-replaceable. It’s rechargeable, but after 400 or 500 charges, it starts to hold less juice. Eventually, you’ll have to pay Apple to install a new battery. (Apple says the added bulk of a protective plastic battery compartment, a removable door and latch, and battery-retaining springs would have meant a much smaller battery—or a much thicker iPhone.)

Battery Life Tips

The battery life of the iPhone is either terrific or terrible, depending on your point of view—and which model you have.

If you were an optimist, you’d point out that the iPhone gets longer battery life than most rival touchscreen phones.

If you were a pessimist, you’d observe that you sometimes can’t even make it through a single day without needing a recharge.

So knowing how to scale back your iPhone’s power appetite could come in extremely handy.

The biggest wolfers of electricity on your iPhone are its screen and its wireless features. Therefore, these ideas will help you squeeze more life out of each charge:

  • Dim the screen. In bright light, the screen brightens (but uses more battery power). In dim light, it darkens. That’s because when you unlock the phone after waking it, it samples the ambient light and adjusts the brightness.

    Note

    This works because of the ambient-light sensor hiding behind the glass near the earpiece. Apple says it experimented with having the light sensor active all the time, but it was weird to have the screen constantly dimming and brightening as you used it.

    You can use this information to your advantage. By covering up the sensor as you unlock the phone, you force it into a low-power, dim-screen setting (because the phone believes it’s in a dark room). Or by holding it up to a light as you wake it, you get full brightness. In either case, you’ve saved all the taps and navigation it would have taken you to find the manual brightness slider in Settings.

  • Turn off WiFi. If you’re not in a wireless hotspot, you may as well stop the thing from using its radio. From the Home screen, tap Settings→Wi-Fi→Off.

    Or at the very least tell the iPhone to stop searching for WiFi networks it can connect to. Carrier has the details.

  • Turn off “push” data. This is a big one. If your email, calendar, and address book are kept constantly synced with your Macs or PCs, then you’ve probably gotten yourself involved with Yahoo Mail, Microsoft Exchange (Chapter 15), or iCloud (Chapter 14). It’s pretty amazing to know that your iPhone is constantly kept current with the mother ship—but all that continual sniffing of the airwaves, looking for updates, costs you battery power. If you can do without the immediacy, then visit Settings→Mail, Contacts, Calendars→Fetch New Data. If you turn off the “Push” feature, and set it to Manually instead, then your iPhone checks for email and new appointments only when you actually open the email or calendar apps. Your battery goes a lot further.

    These days, non-Apple apps can check for frequent updates, too: Facebook, Twitter, stock-reporting apps, and so on. Your best bet on battery life, then, also involves visiting the Notification Center (The Notification Center), tapping each app’s name, and turning the Notification Center switch Off. That way, your apps won’t use power by frequently checking online to see what’s new.

  • Turn off Cellular Data. This option (in Settings→General→Cellular) turns off the cellular Internet features of your phone. You can still make calls, and you can still get online in a WiFi hotspot.

    This feature is designed for people who have a capped data plan—a limited amount of Internet use per month—which is almost everybody. If you discover that you’ve used up almost all your data allotment for the month, and you don’t want to go over your limit (and thereby trigger an overage charge), you can use this option to shut off all data. Now your phone is just a phone.

  • Turn off the cellular voice circuitry, too. In Airplane mode, you shut off both WiFi and the cellular radios, saving the most power of all. See Airplane Mode and WiFi Off Mode.

  • Turn off GPS checks. In Settings→Privacy→Location Services, there’s a list of all the apps on your phone that are using your phone’s location feature to know where you are. (It’s a combination of GPS, cell-tower triangulation, and WiFi hotspot triangulation.) All that checking uses battery power, too.

    Some apps, like Maps, Find My Friends, and Yelp, won’t do you much good without knowing your location. But plenty of apps don’t really need to know where you are. Facebook and Twitter, for example, need that information only so that they can location-stamp your posts. In any case, the point is to turn off Location Services for each app that doesn’t really need to know where you are.

    Tip

    In the list of apps under Location Services, tiny icons show you which apps are using GPS right now (the appears in purple), and which have used it in the past 24 hours. These icons can help guide you in shutting off the GPS use of various apps.

  • Turn off Bluetooth. If you’re not using a Bluetooth headset, then for heaven’s sake shut down that Bluetooth radio. In Settings, tap Bluetooth and turn it off.

  • Turn off the screen. You can actually turn off the screen, rendering it totally black and saving incredible amounts of battery power. Music playback and Maps navigation continue to work just fine.

    Of course, if you actually want to interact with the phone while the screen is off, you’ll have to learn the VoiceOver talking-buttons technology; see VoiceOver.

Last battery tip: Beware of 3-D games and other graphically intensive apps, which can be serious power hogs. And turn off EQ when playing your music (see EQ (Equalization)).

The Home Screen

The Home screen is the launching pad for every iPhone activity. It’s what appears when you press the Home button. It’s the immortal grid of colorful icons.

It’s such an essential software landmark, in fact, that a quick tour might be helpful.

  • Icons. Each icon represents one of your iPhone apps (programs)—Mail, Maps, Camera, and so on—or a folder that you’ve made to contain some apps. Tap one to open that program or folder.

    Your iPhone comes with about 25 icons preinstalled by Apple; you can’t remove them. The real fun, of course, comes when you download more apps from the App Store (Chapter 8).

  • Badges. Every now and then, you’ll see a tiny, red number “badge” (like ) on one of your app icons. It’s telling you that something new awaits: new email, new text messages, new chat entries, new updates for the apps on your iPhone. It’s saying, “Hey, you! Tap me!”

    image with no caption
  • Home-page dots. As you install more and more programs on your iPhone—and that will happen fast once you discover the App Store—you’ll need more and more room for their icons.

    The standard Home screen can’t hold more than 24 icons (20 on the iPhone 4S and earlier models). So where are all your games, video recorders, and tip calculators supposed to go?

    Easy: The iPhone automatically makes room for them by creating additional Home screens. You can spread your new programs’ icons across 11 such launch screens.

    The little white dots are your map. Each represents one Home screen. If the third one is “lit up,” then you’re on the third Home screen.

    To move among the screens, swipe horizontally—or tap to the right or left of the little dots to change screens.

    And if you ever scroll too far away from the first Home screen, here’s a handy shortcut: Press the Home button (yes, even though you’re technically already home). That takes you back to the first Home screen.

    Tip

    The very first dot, at the far left, is actually a tiny magnifying glass. It represents the Spotlight (search) screen described on Speak!. It’s always waiting for you “to the left” of all the other Home screens.

  • The Dock. At the bottom of the Home screen, four exalted icons sit in a row on what looks like a polished glass tabletop. This is the Dock—a place to park the most important icons on your iPhone. These, presumably, are the ones you use most often. Apple starts you off with the Phone, Mail, Safari, and Music icons.

    What’s so special about this row? As you flip among Home screens, the Dock never changes. You can never lose one of your four most cherished icons by straying from the first page; they’re always handy.

  • The background. You can replace the blue, ripply background (behind your app icons) with a photo. A complicated, busy picture won’t do you any favors—it will just make the icon names harder to read—so Apple provides a selection of handsome, relatively subdued wallpaper photos. But you can also choose one of your own photos.

    For instructions on changing the wallpaper, see Print.

It’s easy (and fun!) to rearrange the icons on your Home screens. Put the most frequently used icons on the first page, put similar apps into folders, reorganize your Dock. Full details are on Organizing Your Apps.

Notifications

A notification is an important status message. You get one every time a text message comes in, an alarm goes off, a calendar appointment is imminent, or your battery is running low. For years, iPhone notifications appeared in a blue bubble, as shown below at left.

Trouble was, more and more apps began to use this mechanism. You’d get a blue bubble when your friends posted updates on Facebook or Twitter. When your flight was two hours from takeoff. When a new Groupon discount became available. When your online Scrabble partner made another move.

Each time, whatever you were doing was interrupted by the appearance of a new blue bubble—and you couldn’t return to your activity without tapping, for example, OK or Cancel or Reply. It drove people quietly insane.

So these days, you can choose one of three notification styles for each individual app. To see these controls, open Settings→Notifications. Scroll down and tap the app you want to tweak. The options for each app vary, but you almost always get these three choices:

image with no caption
  • None. If certain apps bug you with news you really don’t care about, you can shut them up forever. Tap None.

  • Banners. This option is illustrated above at right. It makes incoming notifications appear quietly and briefly at the top of the screen. The message holds still long enough for you to read it, but it doesn’t interrupt your work and goes away after a few seconds. Banners are a good option for things like Facebook and Twitter updates and incoming email messages.

    Tip

    If you can tap that banner with your finger before it disappears, you jump directly to the app that’s trying to get your attention.

  • Alerts. A blue bubble appears to get your attention. You might use this option for apps whose messages are too important to miss, like alarms, flight updates, and text messages.

Tip

While you’re here, you may as well check out the Badge App Icon switch for each app. A badge is the little that indicates how many messages or updates are waiting inside that app—and you can turn it off for each app individually. Some apps even offer an on/off switch for Sounds, which is handy if you think your phone makes far too many bleeps and burbles as it is.

The Notification Center

No matter what kind of notification pops up, you still see only one alert at a time. And once it’s gone, you can’t get it back. Or can you?

Meet the Notification Center screen. It lists every notification you’ve recently received, in a tidy, scrolling list.

You can check it out right now: Swipe your finger down from the top of the iPhone’s screen. The Notification Center pulls down like a classy black window shade, printed in white with every recent item of interest.

Here you’ll find all your apps’ notifications, as well as your missed calls, recent text messages, reminders, and upcoming calendar appointments.

image with no caption

You can have all kinds of fun here:

  • Swipe upward inside the list to scroll through more of it.

  • Drag the ribbed bottom handle upward to make the window shade snap up again, hiding the Notification Center.

    Tip

    Actually, you don’t have to aim for the ribbed handle. You can just swipe upward from beneath the screen, quickly and sloppily.

  • Tap a line in the Notification Center to open the relevant app for more details—for example, to see more information about that appointment, or to read the whole text message in context.

  • Tap the next to an app’s name and then tap Clear to remove that app’s current listings from the Notification Center. (That app’s heading will reappear here the next time it has anything to tell you.)

  • You can fire off a witticism to Twitter, or post a status update to Facebook, right from the Notification Center.

    Just tap Tap to Tweet or Tap to Post—buttons that are new in iOS 6. A “sheet”—a miniature dialog box—appears where you can type or dictate your brilliant thought; then tap Send (for Twitter) or Post (for Facebook). Boom—you’ve just shared your genius with the world, without having had to open some special app, log in, or waste any time at all.

    These buttons work only if the phone knows your Twitter or Facebook name and password (in Settings→Twitter and Settings→Facebook).

Tip

If you don’t use Twitter or Facebook, then you can reclaim the screen space by hiding them. In Settings→Notifications, tap Share Widget and turn Notification Center Off.

Customizing the Notification Center

You can (and should) specify which apps are allowed to junk up your Notification Center. Open Settings→Notifications to see the master list, with one entry for every app that might ever want your attention.

Tip

As you scroll through the list of apps, choosing which you want to appear in the Notification Center, don’t miss the two oddballs: Weather Widget and Stock Widget. If you tap one and turn its top switch On, you’ll see the local conditions and a forecast, right there on the Notification Center; the Stock widget will display a scrolling ticker of stocks you’ve selected in the Stocks app (Chapter 9).

Actually, the first thing you see in this Settings pane is the Do Not Disturb control. It’s a great feature, but you can worry about it later (like when you get to Remind Me Later); it has nothing to do with customizing the Notification Center.

Here, on the master Notifications screen, you can also specify the order of the various apps’ notifications in the center. If you tap By Time, then the apps with the newest alerts appear at the top. But if you tap Manually and then Edit, you can drag the handles up or down to specify the top-to-bottom order of your apps’ notifications on the Notification Center screen.

image with no caption

Tap an app’s name to open its individual Notifications screen (above, right—the Draw Something app, in this example). Here, you can, if you like, turn Notification Center to Off.

The app’s name will no longer appear in the upper list of apps, which bears the obvious heading “In Notification Center.” It’s jumped to the lower list, called “Not in Notification Center” (duh). The app can still get your attention with banners or alert bubbles—but it won’t appear in the Notification Center.

Tip

You can also use the Show button to specify how much of the Notification Center this app is allowed to use up—that is, how many lines of information. Maybe you need only the most recent alert about your upcoming flight (1 Item), but you want to see a lot more of your upcoming appointments (10 Items).

Messages on the Lock Screen

The Lock screen (Locked Mode) is another place to see what’s been trying to get your attention while the phone was in your pocket: missed calls and texts, new messages and email, and so on. (You can see a picture on The Lock Screen.)

The Lock screen may seem just like the Notification Center—but there are differences. For example, every time you wake the phone, whatever notifications are on the Lock screen are wiped clear. They don’t stay put, as they do on the Notification Center.

You might want a different set of apps to list their nags on the Lock screen. Maybe you want the Lock screen to show only missed calls, new text messages, and new mail—but you’d like the Notification Center to be fully stocked with Twitter and Facebook updates, for example. That’s why, when you burrow into Settings→Notifications and tap an app’s name, you get a View in Lock Screen on/off switch.

Miscellaneous Weirdness

As you poke around in the Notification Center settings, you’ll discover that certain oddball apps offer some options that don’t match up with the settings you see for most apps. Don’t freak out. It’s all part of Apple’s master plan to put controls where it hopes you’ll find them.
