Back at WWDC Apple unveiled perhaps the biggest change to its mobile OS. iOS 7 brings in an entirely new experience for all compatible iDevices thanks to its revamped interface and a ton of new features. After having gone through several beta the final version is nearing completion.
iOS 7 will be available publicly on September 18th. You will be able to download it on an iPhone 4 or later, iPod Touch 5th generation, iPad 2 and later and iPad Mini.
