Now that we are all reading electronic versions of your book is it possible for you to make arrangements with somebody (Amazon??) to make updated versions available when you discover errors or minor improvements to your code that need to be addressed? (I shutter to think what problems a novice [in iPhone development] like me will have after iOS 5 is released.} Maybe this would only be possible if your book was sold through Apple’s iBooks. It would be so nice to see “Update Available” displayed, and have the updated version of your ebook downloaded.
Thanks for taking the time to write your book.
P.S. It was cinek2’s suggestion that I create a new topic. Thanks for the idea, cinek2.
