Ebook: iPhone SDK development: building iPhone applications

Wanted to develop an iPhone application, but had never done any iPhone or even Mac programming before. Excellent step-by-step instructions and detailed examples. Well tested sample code and examples that were surprisingly deep and useful. Can't say enough about how good this book really is. Took me from being a rookie to someone who can now effectively develop - and have enough background to use the Apple reference material to get to the next level.
