If you have accidentally upgraded your unlocked iPhone 3G to 3.1 3 firmware and lost your unlock because of the Baseband changes, here is a good news for you.

FuzzyBand is a Cydia App which can downgrade your iPhone baseband from 05.12.01 to 04.26.08.

It has a limitation that it works only for iPhone 3G running 3.1.3 firmware with older boot rom 05.08 and not for iPhone 3G with newer boot roms. It also does not work for iPhone 3Gs.
