The Safari-exclusive applications for iPhone and iPod touch assemble various elements, and this book shows you how to integrate these elements with key design concepts and principles in order to develop a highly usable interface for the touch screen. You'll learn to use existing open-source libraries in your code, imitate the overall look and feel of built-in Apple applications, and migrate existing Web 2.0 apps and sites to this new mobile platform. By the end of the book, you'll feel untouchable as you create a custom mobile application from scratch.
