Unlock iPhone 3.1

Every time a new iPhone OS comes out, it gives headaches to jailbreakers and unlockers. This time is no exception to the rule… The new iPhone OS 3.1 has been available for a few weeks and the Dev Team has successfully been able to unlock it.

It took a while but all 3 iPhones (iPhone 2G, 3G, and 3GS) can now be unlocked. You will either need to use PwnageTool or UltraSn0w to unlock your iPhone, depending on the model.

In order to unlock your iPhone, you will have to jailbreak it first. Click this link for more information on how to jailbreak iPhone 3.1.

I will be updating this article with new iPhone 3.1 unlock information as it becomes available. For the latest unlocking info, check out our unlock section and don’t forget to follow me on Twitter.

Unlock iPhone 2G 3.1

So far, there is only one way to unlock the iPhone 2G running the 3.1 firmware. You have to use PwnageTool, which only works for Mac OS X. Follow this step by step tutorial to unlock your iPhone 2G with PwnageTool. A Windows version is in the works and it should be available in a few days.

Unlock iPhone 3G 3.1

You can unlock your iPhone 3G 3.1 with UltraSn0w. First, jailbreak your iPhone then:

  • Launch Cydia.
  • Add the following source to Cydia repo666.ultrasn0w.com (note there is a “0″ in sn0w, not an “o”).
  • After installing this source in Cydia, search for “ultraSn0w”.
  • Install UltraSn0w and reboot your iPhone.

Unlock iPhone 3GS 3.1

Just like the iPhone 3G, you first have to jailbreak your iPhone 3GS (see tutorials) and then install UltraSn0w from Cydia.
