iOS 5.0.1 is out from past couple of weeks but still an Ultrasn0w update has not been released in order to unlock iPhone 3GS with BB 6.15.00 on it. A lot of users who restored iOS 5.0.1 on their iPhone 3GS but rely on unlock were stuck with a “No Service” error on their Home Screen. Yesterday we posted about Ultrasn0w fixer which is a third party solution to unlock your iPhone 4 and iPhone 3GS on iOS 5.0.1 but that solution is having some problem. Some people were getting dependency issues and even developers of that tweak refused release a fix for it.
Anyhow, folks over BiPR came up with a brilliant manual Ultrasn0w patch which will fix ultrasn0w 1.2.4 and make it work on iPhone 3GS running iOS 5.0.1. Don’t panic it’s an easy process and we tried it personally and we can confirm that it works for iPhone 3GS iOS 5.0.1.
Important: By following this method you can ONLY unlock iPhone 3GS running iOS 5.0.1 with iPad’s baseband 6.15.00 (which most of iPhone 3GS users are running now). DO NOT try it on iPhone 4.
