The iPhone Dev-Team has released UltraSn0w 1.25 which brings iOS 5.0.1 support to the unlock for older compartible basebands.

iPhone Dev Team’s iPhone 4, 3G, and 3GS software unlock, now with added PwnApple. Compatible with iPhone 4 baseband 01.59.00 and iPhone 3G/3GS basebands 04.26.08, 05.11.07, 05.12.01, 05.13.04 and 06.15.00! Thanks to @sherif_hashim and @Oranav for contributing baseband crashes
