    Hi Guys,

    I have no idea what jailbreak and firmware is

    I have a 3g version 2.2. The fone works fine and i can make calls. I want to upgrade it to 3.1. However, I cant do it through itunes as i didnt buy it from the apple store. My friend says it will get locked if i do it.

    Pls help

    You can update and keep your unlock.

    Here's what you should do:

    First, connect your phone to your computer and use iTunes to update your phone to 3.1.2

    Next, follow this tutorial carefully: http://www.iclarified.com/entry/index.php?enid=5885

    It involves you downloading a piece of software called Blackra1n, running it on your PC with your iPhone connected, then running some software that it installs on your iPhone. It's pretty easy.

    Open the Blackra1n App on your phone, hit cydia then hit install. For themes, install winterboard and your selected theme off cydia.

    And for the unlock, include sn0w as well. That's an option when you run Blackra1n.app on your phone.

    I'm currently on 2.2 with an unlocked/jailbroke iphone 3g.
    Would i use the same method as the above? (update, then blackrain)
    Will this guarantee my unlock, with the latest firmware? (whatever that is)

    Thanks

    You could, but there's a new version of RedSn0w out which is probably a bit more foolproof:
