I got a lot of amazing things coming to you all soon. think bigger than jailbreak ;)
In March, p0sixninja revealed that he had found the exploits necessary to release a new jailbreak; however, as expected, he decided to hold those back for iOS 7 or iOS 7.1.
His new announcement hints at something better than a jailbreak which suggests that perhaps he has found a bootrom exploit.

The exploit made those devices permanently vulnerable to a tethered jailbreak.
