It's PSN server maintenance time again. Sony has confirmed that the Playstation Network will be offline from 4:05 PM tomorrow afternoon until 02:00 AM Friday Morning (GMT), which means that you won't be able to play online unless you log in before that time.
In other PSN news, Firmware Update 3.70 rolled out today. This latest version adds cloud saving and Trophy syncing functionality for Playstation Plus members. According to the Playstation Blog, the "Automatic Update will now automatically sync selected save games to your cloud storage and will also automatically sync your trophies with the server each time auto update runs." Good to know - if you're a Plus subscriber.
