Apple released the iOS 5.1.1 firmware two days ago featuring bug fixes and improvements while taking HDR photos. When the iOS 5.1.1 firmware was released we told you to stay away from updating if you relied on a Jailbreak or Unlock. Although we issued a warning, I am sure there are still a select group of people who went ahead and updated anyways.
This isn’t as big of a deal for Jailbreakers, but if you rely on an unlock for your iPhone then not being able to connect to your carrier obviously poses a significant problem. In most cases you should just be able to reinstall UltraSn0w, but because it has not been updated yet this leaves you only one other option – UltraSn0w Fixer for 5.1.1.
What UltraSn0w Fixer for 5.1.1 does is it allows you to unlock your iPhone 4 or iPhone 3GS running iOS 5.1.1 on the following basebands 01.59.00, 04.26.08, 05.11.07, 05.13.01, 05.12.01, 06.15.00. You must also be Jailbroken tethered on the iOS 5.1.1 firmware using RedSn0w 0.9.10b8b. Thus, in this how to guide from iJailbreak.com you will learn how to unlock your iPhone 4 or iPhone 3GS on the iOS 5.1.1 firmware with UltraSn0w Fixer for 5.1.1.
