How to unlock iPhone 4 / 3GS on 5.0.1?  As most of you know that iPhone Dev-team didn't updated ultasn0w to support iOS 5.0.1 so far. Some hackers have successfully developed a fix to unlock iPhone 4, 3GS on iOS 5.0.1. Let's see how after the jump.

Important Note: You MUST have a jailbroken iPhone 4 or iPhone 3GS on iOS 5.0.1 with preserving the unlockable baseband. In the meantime sn0wbreeze is the only jailbreak tool that supports iOS 5.0.1. Current version of Redsn0w, can only jailbreak devices but still does not support preserving baseband for 5.0.1. (You can download Sn0wbreeze from here)

Supported Basebands :
  • 01.59.00
  • 04.26.08
  • 05.11.07
  • 05.12.01
  • 05.13.04
  • 06.15.00

How to unlock iPhone 4 / 3GS 5.0.1 with Ultrasn0w Fixer :

Step 1: First thing is to open up  Cydia from your iDevice.

Step 2: Go for the ‘manage’ >‘sources’ > ‘edit’. Finally to ‘add’, here you paste in the URL:

Step 3: Now you get to the source and you will find two options for ultrasnOw unlocks. One is for iPhone 4 while the other would be for iPhone 3GS.

Step 4: You must opt for the option that best suits you and install it. A reboot would get your application working.

Our Recommendations : we highly recommend to wait until the iPhone Dev-team update ultrasn0w to unlock iPhone 4 / 3GS on iOS 5.0.1 as it will be more stable and free of bugs.

Update: Now you can make iPhone official factory unlock, you can check the details from here
