With older iPads and iPhones (1st gen iPad, 3GS iPhone) if you pressed the screen too hard or anywhere on the bezel, you could see the front move down. I think they used to clip the screen on. This used to cause problems where the screen would click. I just got my 4S. I think they changed how the front is attached to the device, but every time I put on my case I press hard on the front of the device and it scares me. Anything to worry about? Do any of you folks who've had an iP4 have had problems with their front clicking/moving? Should I worry or did they fix this?
