    Default Upgrading Iphone 3G from 2.2 to 2.2.1

    I have a unlocked, jailbroken Iphone 3G and would like to upgrade from 2.2 to 2.2.1. Ive been researching and reading for the last couple of days but different websites and posts say different things. Is 2.2.1 available and safe for iphone 3G? If I upgrade will there be complications? Ive seen a couple of posts where people regretted it and wanted to downgrade. If it is safe and available what would be the safest and EASIEST way to backup my Apple and 3rd party apps and then upgrade to 2.2.1?

    FYI - I currently use Windows Vista and have TMobile as a carrier.

    There arent many differences at all from 2.2 to 2.2.1.
    Is there any reason why you are looking to upgrade?

    Also, if you did want to upgrade, you would need a custom ISPW of 2.2.1 that would disable the baseband upgrade.

    There is an app that I really need to use - would make my life a lot easier and its only compatible for 2.2.1

    What is an ISPW would I go about getting a custom one? Is it safe ...complicated?

    Download FWCHANGER from cydia. That should fix your problem!
    It tricks the phone to thinking your on 2.2.1, when your on 2.2.
    If you have any questions about it. Send me a PM.
