Users diving into Apple's new iOS 6 can get a helping hand from Apple's new guidebook, now available free via iBooks.

The iPhone User Guide For iOS 6 comes packaged as a 153-page e-book detailing all the ins and outs of the new OS. The book is geared for the iPhone, but iPad and iPod Touch owners running iOS 6 can also glean a fair amount of information.

The latest guidebook joins other e-book efforts from Apple, including iOS 5.1 user guides for the iPhone, the iPad, and the iPod Touch. The books are nicely designed, well organized, and easy to follow. The latest book covers all of the features, new and old, in iOS 6, including Music, Mail, Clock, Siri, and Passbook.

Whether you're new to the land of Apple or you're an experienced iOS user, the book will shed some helpful light on how to use the new OS to its full potential. If Apple follows its previous pattern, we should also see additional e-books focused on iOS 6 for the iPad and for the iPod Touch.
