These are instructions on how to perform an untethered jailbreak of your iPad 2 running iOS 5.0.1 using Absinthe for Windows.
Warning***: Before you continue make sure to do a backup of your device in iTunes as you may lose your Camera Roll during this process.
Download the latest version of Absinthe from here.
Double click to extract the downloaded archive and launch the Absinthe application.
As prompted, connect your iPad 2 to the computer via USB. Make sure to remove any passcodes or VPN settings you've previously set.
Click the Jailbreak button to begin
The application will take you through several steps of the jailbreak: Sending initial data, waiting for reboot, waiting for device to finish booting, Preparing jailbreak data, and Sending payload data.
You will be informed that the jailbreak is 'Almost done'.
On you device, locate the Absinthe icon and press it to complete your jailbreak. It could be on any homescreen.
If the server is down and you get an Error establishing a database connection message then tap the Settings icon on your springboard and turn on VPN.
You will get a configuration error; however, after about a minute your device will reboot.
Once your device restarts you will be jailbroken with Cydia on the Springboard!
