    I have a late model 3GS which unfortunately has the New Boot Rom. I am currently running 3.1.2 via tethered blackrain jailbreak.

    I am wondering if by any chance it is possible to downgrade the New Boot Rom to the Old Boot Rom. Or is there a hardware difference that will not support this?

    Please if there is any information that anyone could give I would love to hear it.

    Sorry dude, thats not possible. The boot ROM is a hardware based chip, which you can't change.
