So I've had my bumper case since the release of the iPhone 4 and used it most of the time. I switch between the bumper and belkin grip vue every couple of days. Well I went to take it off yesterday sliding the bottom down first and heard a loud snap. At first I was thinking I damaged my phone, but then realize it was my case. So just wondering if anyone else had this problem? Would apple just exchange if they have more in stock?
