anyone else notice that in iOS 5.1 to unlock the camera you swipe up just like the WP7 and has the same bounce animation if you don't do it fast enough or far enough?
if you just touch the button the screen bounces up a little to indicate to you that you need to slide/swipe up to launch the camera app. I watched it on friend's iPhone. at first he was confused and thought something was wrong with his phone.
