On Wednesday, Apple released the User Guide for iOS 7, currently available for the iPad and iPod touch. The iBooks are essentially iOS-optimized recreations of the manuals Apple already provides for its devices in PDF format on its website, though these newest have iOS 7 interfaces pictured within.
The manuals lay out the physical controls and components of the iPad and iPod touch, as well as the assorted ports and outputs. Much of the remaining content deals with iOS 7. On the iPad, the manual lays out the gesture controls unique to Apple's tablet, such as swiping up with four fingers to bring up the multitasking interface.
The books are both available as a free download from the iBookstore. They require an iPad, iPhone, or iPod running iOS 4.3.3 or later with iBooks 1.5 or later installed.
The iBooks app itself has also seen an update, bringing it to version 3.1.3. That update adds improved compatibility with iOS and iCloud, though it does not appear to sport anything in the way of an aesthetic redesign, as the interface retains the skeuomorphic bookshelf that has typified iBooks since its debut.
Apple has also begun rolling out new versions of selected in-house apps that reflect the "flat" design aesthetic of iOS 7. Both the AirPort Utility and the Apple Store app saw updates on Wednesday, adding compatibility and optimization for iOS 7. The Apple Store app also features a refined user interface.
Apple will likely be rolling out similar updates for its other in-house apps in the near future, but many of those apps still sport the skeuomorphic style that Apple abandoned with its latest iOS update.
The updates are available as free downloads in the App Store. AirPort Utility version 1.3.2 is an 8.4MB download requiring an iPad, iPhone, or iPod running iOS 5.0 or later. Apple Store version 2.8 is a 6.6MB download requiring an iOS device running iOS 6.0 or later.
Apple has also updated the Terms and Conditions for iTunes to reflect the addition of automatic app updates, the App Store's new Popular Near Me feature, and the Touch ID fingerprint sensor built into the iPhone 5s. With regard to Touch ID, the new terms read:
"In order to purchase and download iTunes Products from the iTunes Service, you must enter your Apple ID and password or use Touch ID to authenticate your Account for purchases."
