I used redsn0w to jailbreak my iPod touch 2G. I put it into DFU mode, then opened redsn0w.exe and let it do its work. It showed some hard drive, then the quikpwn logo and a status bar. When it finished, the Apple logo popped up and it's been there for 4 hours. When I go to iTunes, it freezes. iTunes only works when I unplug the iPod. PLEASE HELP!
