I got the iPad 2 as soon as it came out, so I've been using it for a few months now. Starting a few days ago, it's like the up volume side of the button gets stuck, so I can't turn it down and it blasts my ears whenever the iPad itself shifts position. I feel like I need to pick the button out of the up side, but I don't want the button to pop off altogether. Is this happening to anyone else?
