As promised at the conference returned to Apple , on September 10, the new version of the mobile OS from Apple is available for download. The availability of the update started last night, but the servers quickly found themselves under saturated demand. This morning, the procedure is done without problem. Devices compatible with iOS 7 are of course the iPhone 4, 4S and 5, the iPad 2 from (including mini) and iPod 5G. If your device has not yet been offered the download, simply go to the settings on the General tab and then Update. This major update introduces a revival of a point of view interface, taking a turn to the flat design. More colorful, but the system retains its typical ergonomics and its accessibility. New features also appear, some even responding to requests from users. Among these, there is a control center available with a simple swipe of the finger from the bottom to the top of the screen. It provides quick access to several functions, among flashlight mode or shortcuts to the camera. Upcoming iPhone 5c and 5s sold starting tomorrow, Friday, September 20, to embark this new office update.
