Hey, I want to jailbreak my Ipod Touch. It's a 3rd generation MC model with the IOS 4.1 firmware. I have no idea how to do it though. I youtubed it and a couple videos said that it doesn't work with MC models. How can I jailbreak my itouch? Also, if I do jailbreak my itouch and I want to go back to the IOS 4, will it delete all of my music and videos? Thanks!
