Apple has launched the all-new iOS 7, featuring a radically overhauled interface, new Control Center, transparent animations and more.
The new system will be available for the iPhone 4, iPhone 4S, iPhone 5, the iPad 2, iPad third and fourth generation, the iPad mini and the iPod touch fifth generation, likely due to some of the more powerful needs of the new OS.
The last major iOS 6 update for Apple's mobile devices was mostly hit, but there was a big Maps-shaped miss.
Lots of people were rightly angry about Apple ditching Google data, but beyond that mis-step there were things to like: a more useful Siri (App launching plus the recognition that a world exists outside of the USA), shared Photo Streams, handy Phone app controls such as 'send to voicemail', and major improvements to Mail, Safari, accessibility and the Camera app
iOS 7 was officially announced at WWDC 2013 this past week, to a lot of fanfare. Heavy.com reviewed iOS 7 and we loved it, even though the beta version that was released is still a little buggy (but those are kinks that should be worked out by the time Apple releases the full version of iOS 7).

    Apple made multitasking much better in iOS 7. Taking a cue from the jailbroken iOS 6, Apple has decided to let users see full previews of their open applications, and simply swipe up to close them.

    The camera app has been completely rewritten. There are four modes available - Video, Photo, Square and Pano. There is no dedicated switch for those, you need to swipe to get to the desired camera mode.

Tap Years and all your shots fill the screen. Each year holds Collections, like your trip to San Francisco. And in that Collection are distinct Moments — photos from Union Square, videos from AT&T Park. So you can find a shot from whenever, wherever, in no time.
