    ok so ive read through most threads and posts about downgrading.
    i have 2 iphones, both 32gb 3gs.
    1 has been successfully jailbroken on 3.1.2, the other i got 2 weeks ago, already on 3.1.3 along with the new modem firmware 5.12.01.
    the 1st phones fine, but as for the new one, its locked to the 3 network (Australia) which is cool by me and not looking to unlock it.
    as most people refer to jailbreaking a phone meaning UNLOCKING/CYDIA isnt what im really after, im just wondering if i can JUST install cydia/rock on this phone without unlocking the network lock.
    ive tried various ways of downgrading the firmware and since this new phones never been jailbroken, is there a way for me to downgrade the phones software and keep the modem firmware the same?
    id like to learn more about this.

    info on the new phone is
    firmware: 3.1.3 (7E18)
    SN: 86947T....
    model: MC133X
    modem: 05.12.01

    thanks.

    just another note real quick.. and i dont know if this makes a difference, but im on the OLD BOOTROM.
    359.3, and not 359.3.2.
    does this change anything?
    or do i need the info on what BOOTLOADER im on...

    The only thing that really matters is that it's a 3GS and that it's on 3.1.3 - that combination means you can't jailbreak.
