p0sixninja aka Joshua Hills has been a troll on the net for the last several months, advertising UnthreadedJB as an attention hog, and raising hope for a possible iOS 6.1.3/6.1.4/7 untethered jailbreak with no actual proof other than childish language. Anything with regards to p0sixninja should be ignored until it's fully released, analyzed and working. Any sites that has the word jailbreak in the hyperlink are generally scams, meaning this site is no different.
