pretty sure this iPod touch is impossible to jailbreak... MC version 8 GB second gen on 4.2.1... I've also tried 4.1... I've used greenpois0n rc 5,6, and 6.1 as well as redsn0w 9.6 something through a bunch of others... greenpois0n always gives me a failed message, while redsn0w always hangs on waiting for reboot The only thing I've gotten to work is going to recovery mode while redsn0w was hanging. The jailbreak finished, but upon reboot (manually), there was no cydia or anything. I'm about to give up, so if you guys have any suggestions, please give them. Hours of searching has given me no answers.
