New PS3 3.55 Firmware Update Will Fight Jailbreaking
Ever since the Playstation 3 has been Jailbroken, Sony has immediately went to work on fighting the hackers by not allowing the previous dongle sales, adding more security patches as to avoid it, and are probably continuing to think of additional ways to keep the PS3 hack free.
The previous PS3 Jailbreak was done using an external USB dongle which provided the ability to back up games into an external hard drive for later playing. Of course, Sony does not wish that to be possible, for then Playstation gamers could in fact trade games by data alone, without the need of the original disk.
As of now, the only info about the new PS3 Firmware Update 3.55 is that it is supposed to include a security patch, which most likely further fights the PS3 Jailbreaking ability.
