QuickPWN has already managed jailbreaking the iPhone’s 2.2 firmware updates, thanks to the incredible efforts of their own developer team. QuickPWN 2.2 is already available for free for both Windows and Mac users.

Like some of its rivals, Apple has tried hard to fight against jailbreaking with every new software updates in an attempt to keep iPhone subscribers from AT&T’s rival cellular networks, such as T-Mobile.
