Can softra1n unlock iphone4 baseband 4.12.01?

I have an iphone 4 with baseband 4.12.01 ios 5.1.1… Someone please tell me that the software softra1n can unlock it on this baseband… If yes then please give me the source to download it… Your answer would be appreciated…

It's a bit risky using softra1n.i'd head for ultrasn0w. Try searching at www.redmondpie.com

Have not heard of softra1n, try ultrasnow instead.
