Thread: Can a new iPhone 3GS OS 3.1.3 with bb 5.12.1 be downgraded?

    Default Can a new iPhone 3GS OS 3.1.3 with bb 5.12.1 be downgraded?
    Hi guys. I need an advise.
    I planning to get a new iphone 3GS locked to AT&T carrier with OS 3.1.3 and baseband 05.12.1
    So far, there's no unlock for 3.1.3 with baseband 05.12.1 yet.
    Can I do a downgrade to 3.1.2 so that I can jailbreak and unlock it?
    Thanks ahead for the help.

    Sorry for that hahas..
    Cause I've been wondering why some can be downgraded from 3.1.3 to 3.1.2 and unlock them.
    Guess they must be upgraded from 3.1.2 to 3.1.3 and they want to revert it back.
    Need a comfirmation answer and now I got it.
    Thanks ya! Guess I'll have to wait till OS 4.0 to be released and unlock tools to be created by then to unlock my device.

    I see no point of downgrading 3.1.3 firmware with baseband like yours. After that you still can't unlock your phone, so what's the point? Just jailbreak it with spirit. That's all you can do.

    Hmmm, from some forum, they say it can't be jailbreak with spirit too it's a new iphone 3Gs locked to AT&T. Any advise or comment?

    In order to jailbreak the device with spirit the phone needs to be activated. So if you do not have someone with an ATT sim to use breifly then you will have to find one to activate it. Then be able to jailbreak.

    I see. So roughly, I need to activate the phone(unlock it) in order to jailbreak right? Lol. Guess I got no other choice but wait for OS 4.0 to released and dev team release their unlock.

    If you can buy a ATT sim off ebay as others have suggested you can at least activate it to use as a iPod till the unlock comes out.

    Hmmm, does a ATT prepaid sim works? Or I still need a ATT postpaid sim?

    Awww.. Seriously at least activate it so that I can use it as ipod touch at the mean time while waiting for the unlock to be released. Anyone can help on this? Does ATT prepaid sim works for iphone activation?

  13. #13
    yes it can be jailbroken and downgraded with new baseband but one problem is that it well have a carrier lock on it so unless ligit carrier for i phone it well just like an amazing i pod really not a phone lol but im stuck same place

    Lol.. Guess I got no other choice but to wait for the OS 4.0 to be released and hopefully by then dev team will release their unlock. I shall put my coming iPhone 3Gs to sleep at the mean time.

    Because baseband 05.12.01 is currently not unlockable.
