This book has now arrived and I can say that it is indeed excellent. Gives you a good understanding of most of the iPhone libraries, including Application persistence, Application Settings, Multi-touch handling, using the Image Picker, Views and controllers, etc. Audio and 3D graphics are not covered, but I would not have expected these in a book that is pitched at taking you to an intermediate level. No doubt someone will release an advanced book that will address the advanced needs of games applications.
