The PS Vita has a system update
lined up for tonight, preceding Wednesday's mainstream launch. Early adopters can update their systems to firmware version 1.61, which adds a Maps application to the home screen, allows for video recording in the Photos application, and allows for any ratings you make in the PlayStation Store to appear on Facebook. Additionally, the Discoveries screen now lists up to 100 players, as well as the number of times they've been seen.
The Content Manager Assistant app has been updated, and is available now both as a Windows and Mac download. Even if you've got version 1.60 already, you should make the jump to 1.61, as Sony says there are some systemwide performance improvements too. The latest firmware can be downloaded on the console over Wi-Fi, or can be updated from a PC or Mac with the Content Manager Assistant.
