Jailbreak for iphone 2.2.1 is out for both Mac and PC. As expected

The dev team is on the ball, as expected. I never upgraded to 2.2.1 because I did not want to bother with it. Note, QuickPwn has been updated to version 2.2.5-2 for the windows users. Remember QuickPwn and PwnageTool are not the same things.. so read up.

Remember, normal rules apply, dont do this unless you know what your doing, and read the rules!!
