I was playing with Cydia the other day and all of a sudden my ipod froze. Nothing would work and i put it in DFU mode. My itouch is jailbroken and my friend did a while back. I plug my itouch in and it tells me that my ipod is in recovery mode and that i have to restore it. I go and download the 2.2.1 firmware and it doesn't even recognize the firmware. I have tried other firmwares and still the same problem.
