Sony just mentioned on its official PlayStation blog that the PS3 is about to get a "minor" update, v3.56. With Sony about to host a press event in Tokyo, it would be nice if we were getting some new functionality for our update timeout, but apparently all it adds is a security patch (just like 3.55), and for some reason we get the impression that this "security patch" is less about defense against baddies and more about trying to shore up the PS3 jailbreak that's currently running rampant. Of course, there are some serious security concerns when it comes to jailbroken PS3s, like the fact that they allow some serious cheating in select multiplayer games, so a truly competent, non-user-hostile security patch wouldn't be all bad. We guess we'll see what we get when the update lands, presumably later today.
Update: That didn't take long. It's out -- and members of the PS3 hack community already allege that it breaks custom firmware.
