Help I tried to upgrade my ipod touch 2g to 4.0. I downloaded the ispw file and tried to upgrade but in the process it failed. Now I can't even turn it on and when I try to connect it to itunes it doesn't show and says this USB Device not recognized. But then I read a thread to turn it back from the dead and it worked. But when I tried to restore it, it still failed. Then I download the itunes 4.0, since mine wasn't working and that also failed. I really need help on reviving my ipod back.
