iOS7 will be releasing in few hours and before iOS7 release, Apple has released a user guide which is available via the Manuals section from official website. You can download the manuals for the iPhone, iPod touch and iPad devices for free from iBookstore.
iOS7 user manual guide is a 138-page document which covers the basics of iOS7 and it includes each stock app, the redesigned UI and new features such as Control Center and AirDrop. Remember the manual guides are device-specific so the iPhone, iPod touch and iPad will have different guides and each guide accounts the hardware difference like button layout, the form factor and the device setup process and many more.
Right now, user manual guides available only for iPod Touch and iPad and sooner I’ll update the article as soon as an iPhone edition hits the iBookstore.
