I'm very intrigued by jailbreaking, but I want to make sure I can restore effectively if I don't like it (or something is messed up). How do I make sure I have a pre-jailbreaking backup file that I can restore to if needed? Right now there is only one backup file that iTunes creates, and I'm afraid that if jailbreak and then sync, it will overwrite this backup file and I'll never be able to go back. I've read somewhere that even after jailbreaking, when the iphone syncs it will back up only the non-jailbroken stuff. Is this true, or will I always have to restore from my pre-jailbroken file? Thanks for the help.
