iOS Books for iPhone Development

[timROGERS]

I am hoping to learn how to develop for iPhone, and I was wondering if there are any other books I need. I already know PHP and XHTML, so I'm reasonably experience in web development.

I've already bought "Programming in Objective-C 2.0" by Stephen Kochan for learning the basic syntax and "Beginning iPhone Development: Exploring the iPhone SDK" by Dave Mark and Jeff LaMarche.

Are there any other books that would be useful?
