I'd upgraded to 4.1 because I knew that I could use redsn0w for now until greenpois0n worked with my iPod (2G MC - read sig). However, Redsn0w got stuck on "Waiting for Reboot." BEFORE YOU STOP READING: I followed the dev team's instructions and switched USB ports, computers, etc. and it still didn't work. So I downgraded to 4.0, but in the part where I usually select the backup to restore from, it gives me an error message. I disconnected, reconnected, closed and reopened iTunes, and I still get the error. I put a screenshot of it.
Please help!
