Thread: How to upgrade 3g to OS4.1 and keep unlock/jailbreak

    Default How to upgrade 3g to OS4.1 and keep unlock/jailbreak
    I have a 3g phone that is unlocked on T-Mobile and is jailbroken.

    It is:

    3.1.2
    Baseband: 04.26.08
    Bootloader: 6.4
    Model: MB704

    Can I upgrade to the latest OS 4 (is it 4.1?) and still remain unlocked to use on T-Mobile and keep the Jailbreak? I'm finding several of my apps that require OS 4 now.

    I don't want to mess up this phone. Can someone walk me through the steps?

    Thanks!

    I know it's a noobie thing to ask for this kind of help but I don't want to mess up my phone.

    Anyone?

    Just did this very thing. Here's what you do:

    Make sure you're on at least iTunes 9.x--I think >9.1
    sync/backup your phone
    Download the following:
    Official iOS 4.1 for 3G
    Snowbreeze LATEST
    Cook yourself a custom 4.1. Follow available guides as necessary. I prefer to add only Cydia and then later install jb apps. Say yes to (h)activate.
    When the fw is done, it'll be on your desktop. Shift-restore through iTunes.
    When it's done, open Cydia; let it do it's thing; re-open, and install ultrasn0w. I don't think you'll have to add the repo, but you may: repo666.ultrasn0w.com

    Enjoy!
    Quaerite et invenietis.

    Sorry to be a pain....

    Where do I download "iOS 4.1 for 3G"?
    What does "Snowbreeze LATEST" mean?
    What does "cook yourself a custom 4.1" mean?

    I don't understand this! haha

    Thanks!

    Google for the firmware and latest sn0wvreeze means the newest one (2.0.2) and cook means the outcome of the original firmware after sn0wbreeze/pwnage tool

    Hey, I'm on an iPhone 3G and I tried ALL this last night and had no luck. I would reccommend to you not to use sn0wrbreeze. I am on a windows computer and so I can't use Pwnage either. I'm going to wait until 4.2 comes out with a carrier unlock.

    OK, I was going to try today. However, snowbreeze is a PC file. I'm on a mac.

    How about steps for a mac user?
