Sony has just released a new system software update (v4.10) for PlayStation 3, which includes a few minor changes.
First off, once PS3 owners download the new system software, they will be asked to accept a change to our Terms of Service. Sony has already annoucned
plans to unify the PlayStation Network (PSN) and other Sony Entertainment Network services, and users will have to accept their new "Sony Entertainment Network Account," instead of their current "PSN Account." Acording to Sony, this change is one in name only. Users will be able to still play games online, still have access to the latest downloadable games and add-ons, and still experience a wide variety of movies, sports and music across PSN.
With this system software update (v4.10), Sony is also updating the PS3 Internet Browser with improved display speed.
