SONY has released a new firmware which doesn’t do much according to reports, other than patches a few security holes. However, there may be a few things that may appear overtime in this firmware as we’ve in the past seen hidden features/functionality being slipped in firmware updates. I’ve not yet spotted the firmware update on my actual PS3, however. Here are some links to the firmware itself if you wish to download it to USB and install:

FW v3.55 (US) | FW v3.55 (EU)
