Firmware update 3.01 is now available to download for the PS3.
So what does it do, exactly? Sony's official response: "3.01 improves system stability during use of some PlayStation 3 format software."
So which software would that be, precisely? Writing on the US PlayStation blog PSN boss Eric Lempel confirmed, "Yes, this will fix the issues that some users have experienced with Uncharted: Drake’s Fortune."
Uncharted players have been complaining, via the likes of the PlayStation forums, that update 3.0 caused the game to freeze. There were also reports of controller compatibility issues. Looks like all that should be sorted out now though.
