Beginning iPhone 3 Development: Exploring the iPhone SDK
David Mark, Jeff LaMarche
This book is great. However if you have never programmed before, You first need to check out Apress' 'Learn C on the Mac'. Then you should read Apress' 'Learn Objective-C on the Mac'. After that you are ready for this book and will be making your very own professional apps in no time! Remember, this book is third in a series, so if you have very little knowledge in programming, start from the beginning. It is better to learn to walk before learning to run.
