    Wow I haven't been here in a long time! so much has changed. So basically, I have a 3gs that I want to jailbreak/ unlock for my girlfriend. Here is some information

    I don't think I have jailbroken this phone before(I have jailbroken my 2g and 3g, but never my 3gs)

    Model number is MB
    and week build is 44 so i am not sure if i am on new or old bootrom

    i know if i am on the new one, then I can't do anything
    but if I am on the old bootrom, do i downgrade from 4.0 to 3.1.3 then JB then go back to 4.0?

    edit: i am on 4.0 right now and have the latest itunes

    I'm not certain, but I believe that updating the firmware updates the bootrom.

    I also believe Apple isn't signing 3.1.3 SHSH anymore so I don't think you can downgrade.

    If 4.0 isn't directly jailbroken yet, it will be soon. I believe it is for specific devices, but I haven't been keeping track the last couple of days.

    Please correct me if I'm wrong on any of this.
