The latest PS3
firmware update is live, expanding formerly Plus-restricted auto-download features to all PSN users. With this update, you don't need a Plus subscription to toggle on automatic downloads of firmware updates or store purchases.
4.50 firmware also adds the ability to transfer data between a PS3 and Vita via Wi-Fi and ethernet connections - the was previously limited to USB cables. The update also lets you set which group of players (anyone, friends of friends, just friends, or no-one) can see your trophies, and which trophies to show.
