Last July, I jailbroke my 2G iTouch with the redsn0w program. The firmware I was using at the time was 3.0. After it was done, the pinapple logo showed up and everything looked fine. Then suddenly my iPod went to a black screen. I tried to turn it on, nothing. I unplugged it and plugged it back in, nothing. iTunes or my computer won't recognize it. I can't even get it in DFU mode. So I haven't even touched it since that day. So what would be the problem? I heard it could be refreshed by plugging it in to a Mac, but I don't know anyone with one. Thanks alot if you could help.
