Download Ultrasn0w 1.2.7 To Unlock iPhone 4, 3GS On iOS 5.1.1

After a long wait, Ultrasn0w 1.2.7 is here to unlock iPhone 4 and 3GS on iOS 5.1.1. Previously, the Dev Team released version 1.2.5 which supported firmware 5.0.1 but there was no release of famous unlocking tool when Apple released iOS 5.1. This seems to be the reason behind release of version 1.2.7 instead of 1.2.6. In order to unlock iPhone on 5.1, people had to use Ultrasn0w fixer .

Due to complexities involved in unlocking new iPhone 4 and 4S basebands, this updated software based solution supports only old basebands and no new modem firmware is included. If you’re still confused, you can read the list of supported basebands below.

  • 01.59.00
  • 04.26.08
  • 05.11.07
  • 05.13.04
  • 05.12.01
  • 06.15.00

Important Note

Before proceeding to the tutorial to use this tool, you should know that if you’re relying on unlock and want to update to iOS 5.1.1 then you should preserve your device baseband first. You can do this by using custom firmware. You can download custom IPSW for iOS 5.1.1 from here.
