    ok so basics first:

    serial starts 880459
    Model is MC637B
    baseband is on 06.15.00
    iOS is 5.1.1

    originally this phone was unlocked (of which I was not aware), this phone was updated to 5.1.1 from 4.3 and still on 06.15.00 baseband.

    Can I downgrade the 3GS baseband to unlock it?

    The info I provided is about downgrading the baseband.
    Isn't that what you asked for ?
