I don't know what to do, i'm very familiar with the itouch and how it works but i've trieEVERYTHING and can't get it to un-freeze. Litteraly frozen, completely. Recovery mode doesn't work, i can't power down, there's even the previous screen burned onto the background. I don't know what to do. I've even tried plugging it into the computer, but i can't restore because it doesn't detect my device =[ help? Thank ahead of time..
