i tried to jailbreak my ipod with greenpoison (rc6 i believe) for 4.2.1. it said that it couldnt reconize the device ID, and afterwards i exited DFU and now it will not charge. Growl says its connected but iTunes doesnt pop up like it used to every time i plugged it in. i have tried a hard reset and a re DFU/exit. What my be causing this, i have no idea.
