I have a 3GS 4.2.1 with baseband 5.15.04
I want to unlock it & currently there is only the "Upgrade to iPad 6.15.00 baseband" option available.
I know this will "BREAK" my GPS
I have already jailbroken it with Greenpois0n
How do i go about upgrading the baseband to 6.15.00?

Use Redsn0w and check the box to upgrade to iPad baseband. Then install ultrasnow repo and run ultrasnow.
I used the directions in iclarified.com. The only thing that hung me up was on Windows 7 I had to change the affinity permission for redsn0w
