As I reported, the hacker George Hotz, aka GeoHot, was sued by Sony under DMCA for having leaked the private signing key of PS3.
Sony and GeoHot have settled down an agreement. Under this agreement, GeoHot will never again hack any Sony product. See the official press release by Sony.
Interestingly, during this fight in March, Sony succeeded to get a subpoena that allowed them to have access to every IP address that visited GeoHot’s blog since January 2009.
