We first caught a glimpse of Go!Messenger way back in August last year at the Games Convention, and now a mere five months later it's launched in the UK. If you fancy a bit of instant messaging and video conferencing on your PSP, for free at BT WiFi hotspots, then you'll want to pay attention.
Importantly, unlime many the recent additions such as Skype, you'll not need to have a Slim & Lite PSP, with its improved hardware specs, to get on the Go!Messenger gravy train, so there are no limitations. Also importantly there is no cost to actually download the program.
As well as simple text-based instant messaging, Go!Messenger will also allow purchasers of the optional Go!Cam to stream video and audio to any other PSP also using the program. While the appeal of doing so doesn't immediately seem as great as using, say, Skype or Windows Live Messenger, I have no doubt that it will prove popular.
Adding Go!Messenger to the PSP will work exactly like the Skype add-on, in that rather than requiring a software update, would-be users simply download the software to the console and install. You'll have to wait until tomorrow to actually grab the download, which will appear on the PlayStation store.
