This book shows you how to create a new type of iPhone application: hybrid applications written in HTML, CSS, and JavaScript. Hybrid iPhone applications are standalone applications that run like regular applications on your iPhone, but don’t require the files to live on a server on the Internet. Creating hybrid iPhone applications reduces creation time and the learning curve required to get your application into the hands of your customers, because you don’t have to learn Objective-C or have an intimate knowledge of the Cocoa frameworks.
