Unlock iOS 4.3.2 on iPhone 4, 3GS Using Ultrasn0w 1.2.2 [Guide]

by Jawwad in Guides, iPhone, Mobile | 0 comments

After some waiting iPhone Dev team has finally released the latest  Ultrasn0w 1.2.2. It was required because the current version of the Ultrasn0w 1.2.1 was broken on the latest iOS 4.3.2.  It should be emphasized that this is NOT a new unlock for the new basebands but it fixes the issues on already compatible basebands namely: 01.59.00 / 04.26.08 / 05.11.07 / 05.12.01 / 05.13.04 / 06.15.00.

Here is the change log from the developer:

Note that there’s a corresponding update to ultrasn0w, which has been bumped up to v1.2.2 to get along with iOS 4.3.2 (the ultrasn0w update does not include any new baseband support!).  Please reboot your iPhone using the normal “slide to power off” swipe after installing ultrasn0w 1.2.2.

Here is a guide of unlocking the iOS 4.3.2 on iPhone 3GS and iPhone 4 using the Ultrasn0w 1.2.2 after untethered jailbreaking iOS 4.3.2 using PwnageTool 4.3.2 (on Mac) or Sn0wbreeze 2.6 (on Windows).

Before we proceed any further please make sure you understand the following points:

                        • Ultrasn0w 1.2.2 supports unlock for basebands (01.59.00 / 04.26.08 / 05.11.07 / 05.12.01 / 05.13.04 / 06.15.00).
                  • ultrasn0w is NOT compatible with the following basebands (02.10.04 / 03.10.01 / 04.10.01 / 05.14.02 / 05.15.04).
                  • Upgrading iPhone 3GS baseband to the 06.15.00 iPad baseband hack to unlock MAY cause you to lose your GPS!

iPhone 3GS Users: Update iPhone 3GS to 06.15.00 Baseband for Unlock:
iPhone 3GS is required to be jailbroken with 06.15.00 baseband for Ultrasn0w 1.2.2 unlock . Follow the complete guide posted here to update your iPhone 3GS baseband to 06.15.00 and jailbreak it on iOS 4.2.2 before proceeding further.

Now we move to the actual process:

Step 1: First you need to be jailbroken on iOS 4.3.2. Follow our guides to do untethered jailbreaking iOS 4.3.1 using PwnageTool 4.3.2 (on Mac) or Sn0wbreeze 2.6 (on Windows).

Step 2: Now you are jailbroken on iOS 4.3.2 you need to unlock the phone using the Ultrasn0w.

  • Load Cydia on your iPhone.
  • Push the Manage tab at the bottom.
  • Now push on the Sources.

Step 4: Cydia will now automatically update your sources by following a series of automated steps. When the installation is complete search for “ultrasn0w 1.2.2” in Cydia, and install it. It will automatically unlock your iPhone so that you can use it with any carrier without any further action.

Step 5: Finally reboot your  iPhone (using the normal “slide to power off” swipe), and you should now have a completely unlocked iPhone 4 or 3GS, running iOS 4.3.2!
