Thread: Would this work for a 3G?

    Default Would this work for a 3G?
    Okay so I want the 4.1 speed.

    I have an iPhone 3G on 4.0 and i ONLY have a t-mobile sim card.

    If i could borrow a friend's att sim card, could i do this?

    1) Use TinyUmbrella to upgrade to 4.1 ( Not upgrading baseband)
    2) Use att sim card to activate and then use on 4.1 ( Not sure if it works on 4.1)
    3) Download ultrasn0w ( since i have 5.13.04 on 4.0, if i upgrade w/o updating baseband)

    Would this all work?

  2. #2 doesn't work on 4.1; that loophole was closed with 4.0.2. The newest redsnow *kinda* works with 4.1, but there are problems being reported (cydia not working, missing, etc.)

    As of now, there is not a good jailbreak for 4.1 on the 3g.

    You should not restore to 4.1, no jailbreak. If you want speed, downgrade to 3.1.3 again.
