Absinthe Untethered Jailbreak for IOS 5.1.1.
If you are unsure about how to use it or are a bit weary, fear no more. I have quickly rattled up a guide for you. In the words of the Chronic Dev Team "so easy your grandma could do it ;D "
All you will need is Your iDevice plugged in and have the Absinthe tool downloaded.
Step 1) Open iTunes and backup your device (Highly recommended. Nothing is likely to go wrong...but you never know)
Step 2) Open / Launch Absinthe. (If you have a passcode set....remove it or the jailbreak will likely not work)
Step 3) Plug in your iDevice and wait for it to be detected by Absinthe. Once detected, press the jailbreak button, sit back and watch the fun begin.
Step 4) It should look as though the device is restoring then it will say 'Restore complete'. After it resprings, you should have an untethered jailbreak. Enjoy!!
See, So easy your grandma's probably finished before you.
