It may not exactly be the big March update we're waiting for, but it will do for now. Sony has just updated the PS3's firmware to 1.54, and is now available for the guys who've kept their consoles logged on the net.

Aside from the routine security updates, this update now allows console owners to use a compatible USB camera to go with their next video chat session. Read on for the full change list (1.5/1.51 included):
