Ultrasn0w 1.2.8 is now available to unlock iOS 6.1

after the firmware was jailbroken with Evasi0n. However,

for thelatest Apple iOS 6.1 firmware.

Therefore, in simpler turns, the basebands of iPhone 4 and

3GS can be unlocked using ultrasn0w 1.2.8 on
older iPhone basebands.

support the newest iOS 6.1 firmware on your Iphone 3GS and

re-install the tool.
