Firmware version v5.50 for the PlayStation Portable will be released tomorrow, allowing unregistered users to browse the PlayStation Store and do a quick bit of window shopping – you can check out all the latest games, trailers and demos available for download from your PSP. Of course, we still recommend you register at the PlayStation Store, joining the 20 million users that already have, for a greater shopping experience.

The update also allows PSP users to view PlayStation Network’s Information Board on the PSP system’s XMB interface as long as they are connected to an Internet-enabled Wi-Fi connection. This allows users to see the latest PlayStation Store offers immediately.
