Before you get started you should plug your iPad into the computer and sync your iPad ( If your iPad is already Jailbroken, restore it in iTunes before using Greenpois0n). Then, quit iTunes and turn off your iPad.

- Click the Jailbreak button and follow the instructions. This will put your iPad in DFU mode.
- Click the Complete button after Greenpois0n has finished installing. This will exit the computer application.

- Tap on the loader icon then select and install Cydia.
- Once Cydia has installed, you can remove the loader app. You should now have a untethered jailbroken iPad.
