I Have try it many times on my new iPad.. iOS 5.1 issue when closing any notification from notification center drop menu while touching any other part of the screen cause the iDevice to restart and not respond. This the video: http://www.youtube.com/watch?feature...&v=srqJbofZ5FQ wish apple will solve the problem in next update.
Oh nice! I just replicated this. I'm gonna report this to Apple. Because replicating that was so easy they must can figure it out quickly.
I just replicated it too on my iPhone 4S. This is actually the first time I've tried to replicate it. I wonder if the jailbreak devs will create a fix once they release a jailbreak for the iPhone 4S on iOS 5.1.
