In response to the hack the GeoHot released not so long ago, Sony have released a patent. I haven't really had time to read over it and I don't have a clue what it means but here it is: You must login or register to view this content.
I myself have just tried to read through it but I'm afraid I don't understand it. If someone who is more in-the-know could read it and write it in more understandable language it would be much apreciated ;-)
first off it wont affect geohots hack for the ps3,secondly ithink its more of a IBM PATENT
rather then a sony one.Its abit like shutting the gate after the horse has bolted
