Your only chance is: iClarified - iPhone - How to Downgrade Your iPhone 3G Baseband Using Fuzzyband - which probably won't work.

Generally you can't downgrade the baseband - it will still be 05.12.01 - blacksn0w ONLY works with 05.11.07 - on about 1% of early 3G iPhones you can downgrade. Everyone else needs to be very careful about upgrading.

There *might* be a new unlock released for 05.12.01 in late June.

All this has been already asked and answered on this forum many times. This is the definite answer on the subject (as of today). Thread closed
