Pity. They would have been making a lot of money had they release it as open source code. I mean look at how easy Netzke got some bucks from the donations (despite he is not releasing anything yet). But, the greed just got them. It is their worst enemy. Well, good luck for them. I am sure they are a lot of people who didn’t know about PSGroove yet. After all, they are the original founder of the exploit. Gotta give it to them.
P/S: Anyway, their dongles do sucks.
UPDATE: Seems that it is not the orginal PS Jailbreak, but PSJAILBREAKER! Another clone of PS Jailbreak.
