Unlock with Ultrasn0w: A Step by Step

Need to unlock your iPhone? Here is an easy step by step tutorial.

1st, your iPhone must be Jailbroken with Cydia installed. Launch Cydia as seen below:

Allow Cydia to load and update. This may take several minutes. If there is an indicator on the "changes" tab at the bottom, install all changes before continuing.

Now click on Manage at the bottom:

Now click on "Sources"

Now you need to add the ultrasn0w repository by clicking on "Edit" and enter as seen below and hit "Add Source"

Verify the Ultrasn0w Repo is added and now click "Search"

Select "Ultrasn0w" from the results list:

Select "Install"

And now "Confirm"

This process will take a few minutes and you will be asked to reboot your device. Once booted up, you are unlocked and can test this by entering another carriers SIM to the iPhone!!


  1. Thanks for the tutorial.

  2. What SIMS will work? I am going to unlock and sell my phone. Do I leave my old SIM in it or will the buyer use their SIM?

  3. If your selling your iPhone I'd keep your own SIM and let thr buyer use one of his/her own
