After much SpeculAtiOn and rumor, Apple has finally released the iPhone 4 amid fanfare and
excitement. With the new iPhone 4 comes a new OS — iOS 4, which incorporates many enhance-
ments, most notably the ability to support background applications. I was very fortunate to be able
to work with the new OS while it was in its beta phase and even more excited to learn that I would
be working on an iPhone 4 book! Writing a book is always exciting, but along with it come long
hours of hard work, straining to get things done accurately and correctly. For this, I would like to
take this opportunity to thank a number of people who made this book possible.
First, I want to thank my acquisitions editor Scott Meyers, who had faith in me when he signed me
up for this book. Thanks for standing by me and always being there to help. I hope I have not disap-
pointed you. Thank you, Scott!
Next, a huge thanks to Ami Sullivan, my editor, who is always a pleasure to work with. After work-
ing together on three books, we have built up a rapport and totally understand how each other works.
With every new book that I work on with Ami, I learn new things. Thanks for the guidance, Ami!
I should not forget the heroes behind the scene: copy editor Luann Rouff and technical editor
Trenton Shumay. They have been eagle-eye editing the book, making sure that every sentence makes
sense — both grammatically as well as technically. Thanks, Luann and Trent!
Last, but not least, I want to thank my parents, and my wife, Sze Wa, for all the support they have
given me. They have selflessly adjusted their schedules to accommodate my busy schedule when I
was working on this book. My wife, as always, has stayed up with me on numerous nights as I was
furiously working to meet the deadlines, and for this I would like to say to her and my parents: “I
love you all!” Finally, to our lovely dog, Ookii, thanks for staying by our side. Now that the book is
done, we can look forward to an earlier night.
