PSP update in town, so hold onto your calloused thumbs. Firmware 5.50 borrows the PS3's XMB "Information Board" (pictured) for getting PlayStation and PlayStation Store news wherever you've got WiFi and a yearning, and there's also a games information search that works straight from the XMB as well. The update also brings the incredibly tardy ability to browse Memory Stick sub-folders for media, and Trend Micro Security and Safety for protecting the browser from malicious sites and protecting kids from adult content. It's not a landmark update, but it's something.
