So guys here is the another jailbreak tool which will be release soon. Joshua Hill aka p0sixninja, the member of the Chronic dev-team and the hacker behind the Greenpois0n jailbreak just confirmed the release of new version of Greenpois0n RC5 which jailbreak iOS 4.2.1 on iPhone 4, 3GS, iPod touch 4G, 3G and iPad.
p0sixninja replied a tweet to one of his follower:
Unfortunately, Greenpois0n RC5 will be tethered jailbreak for a while due to lack of time, Greenpois0n was scheduled to be release by the new year day but some more kernel patches in sandbox have to be applied, therefore, it has been delayed from its first targeted timeline.
We can expect another Jailbreak for iOS4.2.1. We dont understand why they are burning their Exploits. Geo hot is coming up with his Rubyra1n tool, Dev-Team with Redsn0w. Why are they doing like this? No one will ever understand this story.
