We've devoted six chapters to the biggest of the new APIs, but Core Data is not all that iPhone SDK 3 brings to the table for iPhone developers. A whole slew of new functionality has been made available, including peer-to-peer connectivity, mapping, push services, in-application e-mail, copy and paste, and undo—to name just a few. In the next chapters, we're going to show you how to use several of these exciting new APIs in your own applications, as well as dive into a few more advanced topics such as networking and concurrency.
