    Default Upgrading to iOS4 from 3gs 3.1.3 MC131B
    Hey everyone - I have a 3.1.3 3GS MC131B bootrom and it's jailbroken using Spirit. Just wondering if I can update to iOS4 and if I do can it be jailbroken on iOS4 and with what?

    It depends on your bootrom. There is a good thread at Apple HotTips! | Facebook explaining how to check your BootRom version.

    Ok well you can upgrade to iOS4 if you want. But it will not be jailbrokable yet.

    Any word on roughly when 3gs owners with the new bootroom on 3.1.3 will be able to upgrade to iOS4 and jailbreak?

    Not really no, I know that GeoHot has an exploit that will work on the new bootrom but he may hold off until more people have their iP4's.

    Rumors are about that the Dev-Team are working to JB the new bootrom but I havent seen anything definitive from them, just rumor's. So we'll see.

    Just used the programme f0recast to accurately see what my baseband was. It says that my baseband is 05.12.01 and my bootloader is 6.4 and the model is MC131.

    It says it is Jailbreakable only if SHSH is saved (which it is on Saurkis server on Cydia)

    It says it is not unlockable.

    Under "tethered" it says maybe but depends if it is refurb.

    So....can I upgrade to iOS4 and jailbreak or am I stuck still?

    I bought the phone brand new in March so surely it can't be refurbished?
