Upgrading the iPhone Firmware
Apple provides periodic firmware updates for the iPhone that update the operating system, radio baseband, and possibly other device firmware. Thus far, these updates have not resulted in the loss of any live user data, but do frequently rename files and may occasionally write new ones to the media partition. It is therefore advisable not to update the iPhone’s firmware for forensic purposes, except as a last resort. You’ll have to perform an upgrade only if the device is running an older version of the firmware than is supported by this book (1.0.0 or 1.0.1), and if no other suitable techniques are available to access these older firmware versions in a nondestructive manner.
To upgrade the iPhone firmware to the latest version, use the “update” button available in iTunes. If the most recent version of device firmware is not supported, the closest supported version may be downloaded manually and installed by holding down the Option (Mac) or Shift (Windows) key while clicking the Update button. This will allow the examiner to select the desired firmware file to upgrade to.

This book covers a wide range of iPhone software versions, but you might run into a snag with a particular application if it does not support your version of iPhone software. Do not upgrade the iPhone’s firmware unless absolutely necessary. If an upgrade is required, use the closest supported version to the currently installed version.
The following supported iPhone firmware updates ...
