p0sixninja is working on the development of a new method to jailbreak iPhone 5 and iPad 4, he has made important progress

  You asked me in the last few days when a solution will be launched untethered jailbreak for iOS 6/6.0.1, iPhone 5, iPad 4, iPad Mini, iPhone 4S, etc., but for now no one knows the exact date. What we do know, however, is that at the moment Chronic Dev Team working on the development of a jailbreak solution for iOS 6/6.0.1 and p0sixninja does the same. He is trying to develop a completely new method to exploit iOS, he says it has not been tried before and it could bring a bootrom exploit for future jailbreak solutions.

  Of course, no one knows what p0sixninja is doing, but he claims that he is working alone at the moment, so no matter what he does, he doesn't seem to be helped by anyone. If p0sixninja could discover a bootrom exploit and make it public, then there is a possibility that current iDevices could be untethered jailbroken in the future no matter what version of iOS Apple releases. Of course, for now we only have words and nothing more, but in the past hackers have demonstrated that they can do anything if they have the right motivation.
