Has anyone tried it?
Language towards Sony in the pastebin text is unusually vulgar, and I'd bet that Playsation response via DM is fake. What company would respond with vague threats and smiley faces?
Update: As @jimmyfenix points out the DMs are over the 140 character limit. Lol. Guess the jailbreak could still be real? In any case, installing this sounds like a terrible idea, especially if you ever want to get on PSN again.
