It’s that time again for another one of those barely useful PlayStation 3 firmware updates (I still haven’t forgot about in-game music Sony. At least let me get in-menu music)… But back to the subject at hand. Firmware update 3.30 is now available to be downloaded and it is a mandatory update. Firmware 3.30 includes an updated support for the trophy system and software coding to prepare the PS3 for 3D gaming before the launch of their amazing new 3D Sony Bravia TV’s. Information on the trophy support additions can be found below.
*Trophy enhancements –- Now you can more easily sort trophies in the [Trophy Collection] and [Comparing Trophy] sections. Sorting can be done with [Trophy Collection] in the [Game Category] and also when comparing trophies with your friends in the [Friend Category]
