iOS 5.1 – the concept of a slightly different LockScreen

  In iOS 5.1 Apple modified the LockScreen of our iDevices and it permanently displays the camera button and many people are unhappy with this. A designer believes that it can improve the current design of the LockScreen and changes the shape of the classic buttons with a new, round one that should give us the feeling of something new, something that Apple would never implement. The idea itself is not completely wrong because I for one would like to see a LockScreen designed differently, but would it be enough to change the shape of a single button and the direction in which the decoding is done?
