i was putting on a new invisibleshield, because the old one was old kind of and it didn't look that great and the back was ruined upon application. so i kind of wet it a lot, and then soon on the nano would start turning on while the hold button was on, and the hold button wouldn't work. then after it dried a few hours the thing wouldn't even turn on and then after much playing with it a screen came up with writing about firewire? or something like that and it said like click center to dismiss and i clicked the center button but nothing happened. and all the buttons are broken i think. and then after more playing with it the main screen showed but no matter what i clicked nothing happened. the time displayed on the top changed, but the clickwheel and buttons had no effect. also the hold button now works as you can see the lock in the corner but when you set it back the screen distorted and the lock icon is still there. i reset it, and its just the same thing it went to the main menu but none of the buttons or the clickwheel work. somebody please help me what should i do?! has this happened to anyone before?
