MuscleNerd has announced that the jailbreak developed by chpwn and phoenixdev works on the iPad mini.
the "failbreak" from @phoenixdev @chpwn in action on an iPad-mini :) http://twitpic.com/ba1ega (why failbreak? see @planetbeing's timeline)
Last month, chpwn revealed that his jailbreak for the iPhone 5 would be reserved as a failbreak. That means it will be limited to jailbreak developers and won't be released to the public. This is being done to make it easier to discover new exploits (which will be used for public release) in the future.
Take a look at the image below....
