Jonathan Zdziarski and his editor, Andy Oram, just wrote in with the news that Jonathan’s iPhone Open Application Development book is now available in “rough cut” form. Here are the details:

Certain technologies bring out everyone’s hidden geek, and the iPhone did so instantly upon its release. Thousands of programmers want to provide applications on the iPhone. This book shows them how to achieve the spectacular effects that made the iPhone an immediate hit. The book covers both Apple’s toolkit and an open, community-developed toolkit that has been widely downloaded and used. Author Jonathan Zdziarski, the developer of the first fully functional application using the open iPhone toolkit, now explains in clear language how to create applications using Objective-C and the iPhone API, which in some ways resembles Apple’s desktop API and in some ways strikes new ground. After covering installation of the toolkits and some background about the operating system and Objective-C, the book offers detailed recipes and working examples for everyone’s favorite iPhone feature. Graphics and audio programming, the CoreImage and CoreSurfaces interfaces for games programming, interfacing with iTunes, and the use of sensors are all covered. Any programmer, using this book, can provide applications that impress users just as much as the official iPhone utilities.

For the moment, this version of the book covers the community SDK, but when we have more information on the Apple SDK, it will be updated to cover it.
