They are working on it. The boot rom exploit has been found but the dev team has to work on the jailbreak program to assure that there will be no bugs. Ih8sn0w released the sn0wbreeze jailbreak for 4.1 but later had to update it because there were issues. That jailbreak was not compatible with the iPad, iPhone 4, or the newest iPod Touch. It takes a lot of time to make sure that the software will run smoothly for the amount of people who want to jailbreak. I, like many others, am anxiously awaiting the newest jailbreak for the iPad.
