Thread: [Question] Upgrading 3GS firmware

    Question [Question] Upgrading 3GS firmware
    Hi guys,

    Before you flame me, I know I can find all the needed tutorials for this but I didn't manage to find a clear answer for my question.
    So, I'm on 4.0 on my 3GS old bootrom. I want to upgrade to 4.3.3 and I have a few questions:
    In one of the tutorials I read, was written that if I want to update without upgrading baseband I ned to use PwnageTool - which is Mac only? I don't have a mac. What do I do?
    Currently, my iPhone is activated, not hacktivated, and push is working perfectly without any fix. will I lose it? and if yes, is there any fix?

    btw guys, I really need the help, this is the last 4 hours I'll have my computer for the next 12 days, and I really need the restore.
    Please gimme a hand here.

    thanks in advance,
    Gal.

    You can use snowbreeze 2.7.3 to create a custom firmware of 4.3.3 and restore to it. If you have an official sim to activate, make sure you do not hactivate while building the custom fw.

    I will not lose my ability to unlock, right?

    Nope, you are preserving your baseband by restoring to cfw . You still need to install Ultrasn0w from Cydia after your restore to cfw which is already jailbroken.

    Thanks a bunch, you've been a great help.

    You can close the thread if you may

    EDIT:
    I read a tutorial for sn0wbreeze and they wrote there - Unlockers stay away from sn0wbreeze and official Apple firmware!

    ???????
    thanks in advance!
