How To Unlock iPhone With UltraSn0w 1.2.7

Step 1: You must already be running the iOS 5.1.1 firmware on your iPhone 4 or iPhone 3GS, and you must also be Jailbroken on the iOS 5.1.1 firmware. If your iPhone is not Jailbroken please click here.

Step 2: After your iPhone is running the iOS 5.1.1 firmware and is Jailbroken you will need to simply launch Cydia from your SpringBoard.

Step 3: Once Cydia is up and running you will need to go into the Sources page. To go into the Sources page tap Manage followed by Sources.

Step 4: Typically, the UltraSn0w repo is included with Cydia. If not, tap the Edit button followed by the Add button and you will be prompted to add a URL source. Type:

http://repo666.ultrasn0w.com

Followed by tapping the Add Source button.

Step 5: Cydia will automatically refresh and update sources.

Step 6: After Cydia is done refreshing sources. Tap the Search tab on the bottom tab bar and search for UltraSn0w. Once UltraSn0w appears, tap on it and you should see version 1.2.7. Read through the description and tap the install button to install UltraSn0w 1.2.7 to your iPhone 4 or iPhone 3GS  running the iOS 5.1.1 firmware.

Perquisites: The first thing you need to do before starting this how to is make sure your iPhone is backed up. As the Absinthe Jailbreaking tool was just released, there is a good chance that you may experience an error Jailbreaking it. Thus, it is always a good idea to make sure all your content on your iPhone is backed up.

Recommendation: It is our personal recommendation and Pod2G’s that you restore your iPhone to factory settings on the iOS 5.1.1 firmware. This will dramatically reduce the chance you have of experiencing an error while Jailbreaking it. This is your call however, and is not necessary 90% of the time.

Step 1) – First things first. You will need to download the latest version of Absinthe 2.0 from the iJailbreak Downloads Section or from the direct download link below. It is always recommend that you check the iJailbreak Download Section, however, to ensure that you are downloading the latest version (we do not always update these guides with the up-to-date versions).

When you click the Jailbreak button your iPhone will look like it is being officially restored through iTunes; it should say something along the lines of “restore in progress.”

Note: The Jailbreaking process can take anywhere from 5-minutes to 10-minutes so be patient. If you have not restored your iPhone then it could take much longer depending on the amount of content on your iPhone.
