How To Use UltraSn0w For iOS 5.1.1 iPhone Unlock
Jailbreak your iPhone first either using Absinthe, RedSn0w or Sn0wbreeze.
Usually you may need to add ultrasnow’s repo first. But according on my experience, you won’t need to. Once you’ve installed latest version of Cydia, the required repo will added automatically.
Now launch Cydia app up.
Tap on “Search” button in the bottom right corner
Now search for “UltraSn0w”
Once you’ve found it in the result, tap on it.
You’ll see a details page about UltraSn0w. You may read it or simply tap on the “Install” button followed by “Confirm”.
