I finished up reading the book Beginning iPhone Development and working through most of the examples. Excellent book for developers starting out on the iPhone platform. The book is laid out with examples through 17 chapters or so. The examples are all very relevant to functionalities on the iPhone: accelerometer, autorotation, autosizing, multiview applications, persistence, Quartz, OpenGL ES, gestural interfaces, Core Location, and others. The examples are straightforward to understand and really give you a great taste of what's available with the Apple iPhone SDK. There is nothing in this book about web applications on the iPhone--go elsewhere if you want to learn about that. Looking forward to building and distributing some iPhone apps in the near future.
