iOS 7, the latest version of Apple's mobile operating system, is now available for download. The update can be installed on any compatible iPhone, iPad, or iPod touch by visiting your device's settings menu, choosing "general," and then selecting the software update option. iOS 7 can also be installed with the help of the newly-released iTunes 11.1 on Windows and OS X. (You'll want to download that anyway, as it's required to sync music, videos, and other content to your device.)
The most immediate and striking change in Apple's latest OS is the all-new user interface designed under the eye of Jony Ive. iOS has been given a comprehensive visual makeover intended to make the overall user experience "simpler, more useful, and more enjoyable." But changes aren't just skin deep; iOS 7 introduces new features like iTunes Radio, AirDrop sharing, Control Center, and improved card-style multitasking. We'll have much more to say about iOS 7 soon, but for now it's time to experience it for yourself. Note that not all of Apple's latest features are available across all iOS hardware. If you're running the new software on anything older than an iPhone 5 or iPad 4, you stand to lose out on some functionality. We've charted those differences below.
