Hi! I have a jailbroken 3g iPhone on 2.2. I have downloaded songs and want to transfer them onto my iphone but I'm confused. Whenever I update my iphone, I have to back it up so if I update it right now and back it up, will it erase the backup of my iPhone before I jailbroke it? I don't want to lose my pictures or anything in the future if I have to restore it, like unjailbreak it. & Is it possible to save the pictures and notes on my current iPhone right now but not save the jailbreaking part? Like say, if i were going to restore my phone, can it still have the pictures I took while my phone was jailbroken?
