Actually, there is a Dummy iPhone Dev Book by
Neal Goldstein and is quite good. If you're new to Xcode & Objective C, have no experience with Cocoa and used a Mac for the first time just a few weeks ago, this might be the right book for you.
With separate chapters on Xcode, Interface Builder, Debugger, Instruments, registration with Apple, provisioning and AppStore application there isn't much left for actual code in the book. But as introduction to iPhone development, this is a great book.
There are only two examples, but they both are complete applications and even with only so much code there are a few nice surprises, like the decent take on proper keyboard handling. Seems like everybody is happy with this book as they commissioned Neal Goldstein to write another
iPhone book, this time on more than 800 pages.
Once you're done with it, go with the books by Kochan, Hillegas, Dave Mark and others.
