I have an ipod 2G which I jailbroke way back when it was in the command prompt stage but now I have a friend who is asking me how to jailbreak his 3G I dont have an iphone so I dont want to tell him anything wrong. He has a 3G running 2.2.1 What is unlocking? Is it the same as jailbreaking? Please direct me to the software a I need and if I have to downgrade to 2.2 please tell me how. Thanks for the help.
