I have a iphone 3g with version 3.1.3 (7E18) and i want to unlock it.... the modem firmware is 05.12.01, bootloader version 06.02

I have jailbroke and i have found some video at youtube teach how to use fuzzyband to download firmware. but after i load in fuzzyband it said no supported, it said downgrading will only work with baseband bootlader 05.08.

I want to know is there a way to unlock my iphone so i can use t-mobile.

Not yet. An unlock probably will come eventually, but not at the moment. You can't downgrade baseband either.
