    I currently have an iphone 3g on 4.0, and its unlocked. I want to upgrade to 4.1, and keep my unlock. Can i just upgrade through itunes, and then run limera1n, or will i lose my unlock if i do that? If no, then how can i upgrade without losing the unlock?

    There is a way to update with TinyUmbrella to preserve your baseband, but I'm not sure how. Whatever you do, no NOT upgrade directly through iTunes, as you will lose your unlock for forever, most likely.

    Use sn0wbreeze. You can only preserve your baseband with a custom firmware. Tinyunbrella is supposed to preserve your baseband while you update but I wouldn't try if you REALLY need the unlock. I think someone who doesnt need the unlock should try for us. Anyone willing to update to 4.1 with tinyunbrella active and tell us what BB version you are on after the update?

    Exactly. So pretty much no way to upgrade?

    It is broken? It must be the newest version. If you want the older version I can send it to you. Becuase everyone used sn0wbreeze when that was the only thing to use.

    I used a pwnagetool fimware to update.
