I have an unlocked 1.1.1 iPhone that I have been using for months. I want to upgrade to 1.1.3 but I am assuming that the current state of my iPhone will be basically formatted. Is this how it works? If it is, how do I backup my Notes? Is there a backup all option or something (for my stocks and weather cities, and such)? Any information on backing up (and even the upgrade and unlock) is highly appreciated! Thanks.
