Jonathan Zdziarski is better known as the hacker "NerveGas" in the iPhone development community. His work in cracking the iPhone helped lead the effort to port the first open source applications, and his book, iPhone Open Application Development, taught developers how to write applications for the popular device long before Apple introduced its own SDK. Prior to the release of iPhone Forensics, Jonathan wrote and supported an iPhone forensics manual distributed exclusively to law enforcement. Jonathan frequently consults law enforcement agencies and assists forensic examiners in their investigations. He teaches an iPhone forensics workshop in his spare time to train forensic examiners and corporate security personnel.
Jonathan is also Sr. Forensic Scientist for viaForensics, a Chicago-based forensic consulting firm where,
among other things, he performs penetration testing of iOS applications for corporate
clients. Jonathan gets paid to hack things for a living.

"I had an absolute blast reading this book. What I liked most about the book is that it got down to the knitty-gritty details really fast...If youre curious with tinkering around with the internals of iOS or if youre an application developer looking to secure your application, youll definitely find this book useful. All in all, I highly recommend this book to any developer or security professional."
"...a good starting place for reasonably experienced C and C++ programmers who are interested in jailbreaking their iPhone and moving away from the crowd. At worst youll learn just what the difficulties are."
"...a profound introduction and reference for transitioning to Objective C-based iPhone/iPod touch development. It supplies you with all the necessary information, and it provides a lot of examples for achieving quick success--assuming that you have all the tools properly installed and that you already own a Mac (for development) and either an iPhone or iPod touch."
"This book is in a completely different league from other offerings I've seen. The book is extremely comprehensive, and having so many annotated sample projects will be a boon to iPhone developers. Even experienced developers who aren't familiar with a particular framework will be able to crack open these sample apps and get very clear and concise examples. Jonathan speaks with authority, clarity, and
experience, something that will definitely differentiate this book from other offerings I've seen."
"This book is easy to use both as a reference and for a linear once-over read to familiarize myself with the aspects of iPhone programming. I like the way the sections step through each example, starting from the simplest form to the more complex form where Controllers are used for multiple views, or moving from the use of Interface builder files to custom coding."
"This book proves invaluable for its chapters on the UIKit, a large part of the API that is used to build graphical apps on the iPhone. Great for beginners -- you will be able to confidently build apps that rival the ones included by Apple itself."
"If you need or want to develop for the iPhone -- and you find the restrictions of the Apple SDK onerous -- you can do so today. Zdziarski's iPhone Open Application Development is an excellent place to start, both for its introduction to the platform, and for its documentation of the APIs and frameworks that make the platform run."
"I see this book being a great tool for the person who wants to write their own personal applications for the iPhone, and who doesn't want to live with the restrictions that Apple is placing on the use and distribution of "official" applications."
