Are you a programmer looking for a new challenge? Does the thought of building your very own iPhone app make your heart race and your pulse quicken? If so, Beginning iPhone 3 Development: Exploring the iPhone SDK is just the book for you, and it's now updated for iPhone OS 3. Assuming only a minimal working knowledge of Objective-C, and written in a friendly, easy-to-follow style, Beginning iPhone 3 Development: Exploring the iPhone SDK offers a complete soup-to-nuts course in iPhone and iPod Touch programming. The book starts with the basics, walking you through the process of downloading and installing Apple's free iPhone SDK, and then stepping you though the creation of your first simple iPhone application.

The confusing art of table building will be demystified, and you'll see how to save your data using the iPhone file system. You'll also learn how to save and retrieve your data using SQLite, iPhone's built-in database management system. You'll get started with the major features of Apple's newest iPhone OS 3, which includes in-app purchase, push notification service, peer-to-peer connectivity, and new frameworks for external accessories, maps, media player, and stores. There's a lot to learn, but with Apple's iPhone SDK, this book, and your imagination, you'll have all you need to start building your very own best-selling iPhone applications.
