George Hotz, or "Geohot," is a pioneer in the jailbreak community. He has been the mastermind behind many jailbreak projects, including LimeRa1n and BlackSn0w.
Geohot recently hacked Sony's Playstation 3 and essentially created the ability to "jailbreak" Sony's popular console. Even though it is legal to jailbreak the iPhone, it isn't legal to do the same to a Sony product. Sony took action and filed a lawsuit against Geohot on the basis that what he did "encourages piracy" on their platform.
Needless to say, Geohot is pissed. He is calling on the community and the media to help him in his legal fight against Sony...
