I jailbroke my 2G ipod touch a few weeks ago and everything was going great. I had to even reboot a few times and it worked fine. I installed that Free Memory app from the app store to lessen the amount of times I had to reboot, but today after it tried to clear the memory my ipod just shut off. Obviously it wouldn't reboot itself, but i wasn't at home so it was in my pocket for a while just dead. I plugged my ipod in when i got home and tried putting it into DFU mode... nothing. I have tried to put it in DFU mode many times now, so I am very desperate for help. I downloaded the DFU Helper but it wont open for some reason. Is my ipod bricked? or will i eventually be able to reenter dfu mode?
