My touch was working perfectly and everything was fine until I turned my touch off... When I try to turn it back on, just a blank black screen, nothing's showing. I tried holding power+home for 10 seconds then releasing the power with no success. Plugging it into the computer doesn't help either, it doesn't recognize my touch either, neither does iTunes. My touch was at 3.1.2 and jailbroken using BlackRa1n. iTunes is version 9.1. Please help me, thanks.
