Along with Ultrasn0w 1.2.1 news, we have another good news for jailbreakers. Chronic Dev team member, P0sixninja, has revealed that they have reached to the final stages of GreenPois0n RC6.2/RC7 tool for iPad 2 jailbreak.
The iOS 4.3.1 untethered jailbreak tools, Redsn0w, PwnageTool and Sn0wbreeze, can’t be used to jailbreak the iPad 2 devices, and these tools can only be used on the old hardware devices. iPad 2 comes with better security patches and improved techniques to prevent unauthorized root access, so it becomes difficult to jailbreak this gadget.
However, Chronic Dev team seems to have achieved the breakthrough in iPad 2 untethered jailbreak -
Since 4.3.1 is already exploited by the legendary @i0n1c, we’re working on finishing iPad2 jailbreak now.
