The official PlayStation website might have leaked
information regarding firmware 2.53, but it was clearly very wrong about the date. The update didn't drop on November 26th, as the website suggested, but is instead available right now
. Honestly, it's true. Go check for yourself.
The latest firmware adds full screen functionality to embedded Flash videos in the web browser, as well as generally "improving the way the Flash Player works with the internet browser." Meaning more websites will now work. Overall, a nice, if slightly anemic, firmware update. It's all free though, so we can't complain. Go on commenters, prove us wrong.
