MuscleNerd uploaded a screenshot showing jailbroken iPad 3 running Cydia. Although the new iPad is jailbroken already it might take some time for the developers to release the tool to general public. So if you want to jailbreak your iPad 3 and run Cydia apps you have to wait for a while before you get your hands on the jailbreak tool.
