Apple releases iPhone user guide in iBooks

Apple's "iPhone User Guide For iOS 8" contains an illustrated overview of iOS 8's new features, as well as usability guides for those not familiar with the mobile operating system.

According to the release notes, the guide covers all iPhones from the new iPhone 6 and 6 Plus down to the iPhone 4S. As such, the content is available in the usual rich iBooks format, making for easy on-the-go reading. In addition to iOS 8-specific tutorials, the guide also offers a sneak peek at Apple's forthcoming 4.7-inch and 5.5-inch handsets.

Also included is a deeper look at the Health app, which integrates with third-party apps via HealthKit to work as a repository for motion, medical and wellness data. Apple today said a bug in the initial iOS 8 release is causing issues with HealthKit-compatible apps and the company has subsequently pulled those titles from the App Store. A fix should be in by the end of the month, Apple said.

The "iPhone User Guide For iOS 8" is available as a free download from the iBookstore and can be viewed on Mac, iPhone, iPad and iPod touch models.
