How to jailbreak iOS 5.1.1 by utahman130
Step 1: Make sure you are on iOS 5.1.1. Download Absinthe v2.0.4
here.
Step 2: Connect your iPhone to your computer via USB. Open iTunes, right click your device and click "Back Up". After it is done backing up, quit iTunes.
If you want the jailbreak process to go much, much, faster wipe your phone, but this is not required
Step 3: On your iPhone, go to Settings>General>Auto-Lock and set Auto-Lock to never. Go to the home screen of your iPhone and don't touch it.
Step 4: Launch Absinthe. Wait until it detects your phone. Push jailbreak (YOU DON'T HAVE TO GO INTO DFU MODE!

) and wait. The iPhone will first look like it is syncing with iTunes, then recovering from a restore, and then reboot. You can follow along in the Absinthe window, which will tell you when it is done.
Step 5: Once Absinthe says "Done Jailbreaking", Cydia, the jailreak store, will have a icon on you phone (No Launcher

). Open Cydia up and wait for it to "Install Filesystems". After it does, it will close itself. Reopen it and enjoy your jailbroken iPhone
