Last night I was playing Tap Tap Dance and froze while loading a song. (Technologic by Daft Punk Please Register or Log in to view images). I couldn't do anything, including pressing the home button and power button or DFU mode. So I decided that it would die out of battery soon enough, so I just left it there over night. By morning, it was dead. I tried charging it but that didn't do anything, just the same old black screen. Any ideas?
