iOS 7. Coming This Fall

All-new design

iOS 7 started with a desire to take an experience people love and make it better. To make it even simpler, more useful, and more enjoyable - but still feel instantly familiar. The design of iOS 7 is beautiful because it's all of those things. And it's the start of a new chapter for iOS.

All-new features

Control Center, AirDrop for iOS, and smarter multitasking are just a few of the great new features in iOS 7. And all your favorite apps have been enhanced to make everything even easier to get to and use. So with iOS 7, not only is your device more capable, you are, too.

I can't wait for this fall! I will be downloading iOS 7 on my iPhone 4S.
