iOS 7: Completely new Lock Screen and Interface with video
So the Belgian interface designer Kerroudj Mohamed made two videos how iOS 7 will look like, which the Lock screen of Apple will look completely different. Scroll down for video.
In the second video we see how some basic apps such as the calendar and Music Player can be openend, by tapping at certain spots on the screen. So you can choose another music number by tapping the time.
