    Hey everyone,
    i have an old iPhone 3G that i want to give to my friend. it's jailbroken and unlocked on iOS 3.1.2. i want to update it to 4.2 and completely wipe everything off it. can anyone help with that ? there's a bunch of unlock and jailbreak stuff out there but i can't figure out which to use and in what order. thank you!

    Connect to iTunes and hit restore. If you have the iPad baseband on it, you'll need a custom firmware.

    Before anyone can answer this, what baseband is on it.
    Is it unlocked ? If so, by what method.

    Looks like an Ultrasn0w unlock.

    Honestly, doing an upgrade and preserving the unlockable baseband takes some knowledge of iPhone jail breaking.

    Based on your responses here, I would encourage you not to try it on your own.
