I jailbroke my ipod touch 2g yesterday and my mom found out and made me restore it to the original settings. She says that it errases all the music and stuff off of my ipod, but i didnt have anything on my ipod anymays. She also says it voids the warranty but i dont care. Does it make it so that you cant update your ipod without errasing everything? Anyone that can answer my question or give me advice on wat to do would be greatly appreciated. thanks.
