GreenPois0n 4.2.1 for all iDevice(Soon)

As you know, iPhone Dev Team is working day and night to handle a qualified untethered Redsn0w 0.9.7 jailbreak,on the other side Chronic Dev Team member Joshua Hill behind GreenPois0n jailbreak has confirmed on his Twitter that the team will not release Greenpois0n until it will be untethered jailbreak for iOS 4.2.1 .

p0sixninja: A lot of people are saying another tethered jailbreak is pointless, I agree. Focusing on getting untethered before release

Another point which may beat redsn0w, that this won't require SHHS blobs for 4.2b3 unlike the iPhone Dev Team's Redsn0w 0.9.7, according to a reply for someone asking if it is based on the same exploit Comex working on, and whether or not it will require SHSH blobs for 4.2b3 unlike Redsn0w 0.9.7.
