Apple also rolled out iTunes 11.1 today, an update that adds iTunes Radio, the free advertising-support music streaming service. Users who have paid the $25 annual fee for iTunes Match do not see or hear ads on iTunes Radio.
iTunes 11.1 can be downloaded for OS X and Windows from Apple's website.
iOS 7 can be downloaded over the air from iPhones, iPads, iPad Minis and iPod Touches, or through iTunes. From an iPhone, for instance, users must tap the "Settings" icon, then the "General" button on the resulting screen. Tapping "Software Update" will kick off the update process.
