I have had my 40GB iPod for about 5 months. I have never had any problems with till now and have taken immaculate care of it. However, just recently I found that the left hand side of the steel backing had warped slightly such that it expanded beyond the borders of the white fronting, exposing a very tiny bit of the interior. It is a pretty solid warp too, can't be pushed in manually. Has anyone else had this kind of problem, is it linked to any particular cause or type of use, and can it be remedied, with or without sending it to a technician? Any help would be greatly appreciated.
