    That particular baseband cannot be unlocked, you can't downgrade the baseband either :(

    I don't think the GEVEY SIM works for an iPhone 3GS.

    You can upgrade the baseband to the iPad baseband with Redsn0w then use Ultrasn0w to unlock. The issue is, it may cause GPS malfunction/break. It would also then require you to restore to custom fw on fw 4.2.1 and higher, so you essentially can't use stock firmwares anymore except on 4.1 or below (if SHSHs are available).
