Ultrasn0w Unlock for iOS 4.2.1 Download Available
Ultrasn0w has been updated to ultrasn0w 1.2 which works to unlock iOS 4.2.1 running on the iPhone 3G and iPhone 3GS.

After you download and install ultrasn0w 1.2 you will then be able to unlock your iPhone 3G or 3GS running iOS 4.2.1. This update will allow ultrasn0w to unlock iPhone 3G and iPhone 3GS basebands 04.26.08, 05.11.07, 05.12.01, 05.13.04 and 06.15.00 via the iPad IPSW.
