i was just using my ipod touch as normal, then i slipd it into my pocket and watched tv for a few minutes, thedn i pulled it out and it was stuck on contacts, so i locked it. Then i tried to enter my passcode and it never worked so i locked it again and tried it again. And so I tried to turn it of but it wont turn off. And I accidentally took a screenshot and now i can only lock it and it will show up to be a white screen but when i lock it it just goes black. Please help.
