Late last night, Firmware 3.10 went live for the PlayStation 3 and brought a new way to order photos off the XrossMediaBar as well as three Facebook options you might've missed because they're tucked away under Account Management. Earlier this week, Xbox Live launched Facebook on the Xbox 360.
Over there, you're getting the real Facebook; you can post, comment, look at photos, and so on. Here on the PS3, you're getting none of that. What you can do here is post purchase information, game events, and Trophy information to your Facebook profile.
