    Default Please Help Me Downgrade From 3G 4.0 to 3.1.2
    Ive tried to research on my own and obviously I suck at it. I have a 3g I updated to 4.0 then Jailbroke it. It runs like crap and I want to be back on 3.1.2 but I cant find the firmware anywhere for (Windows) and even if I did I would know how to restore it. Please help me

    Here is the site where I get all of my firmwares since I jailbreak Idevices for friends and family.

    iPod, iPhone and iPad Firmware Download

    And use Blackra1n as you might know to jailbreak it.

    stuck in a similar situation, I was able to downgrade, but it didn't solve any of my problems.

    I'm not sure if there is an unlock for 05.13.04.

    i have blackra1n fixed and i also have spirit to jailbreak, i could care less about unlock seeing as how i am att..... i dont care if i go to 3.1.3 or 3.1.2, they are both the same just jailbreaking them is the different part...... i just want to downgrade so that i can wait untill a later time to upgrade to 4.0 when all the bugs are fixed and there is a simple jailbreak for it..... the 4.0 is messing with my sms and that is the only reason that i am downgrading......

    if you jailbreak with Spirit it is very probable that you won`t be able to jailbreak your iOS4 in future
