The gaming phone has arrived. People, meet the Sony PSP.

Wait a minute. A PSP phone?

In what could a sign of things to come (and to play catchup with Nintendo), Sony and BT have unveiled software for the PSP that will allow video and voice calls and send instant messages. Called Go!Messenger, the software will use the built-in WiFI to connect to home and outside WiFi networks, and use VoIP to route calls.

Will this software finally dislodge the Nintendo DS from the top of the handheld gaming market? Hmm. The US telco market is firmly in the hands of the carriers, and they are doing everything to stamp VoIP out of the earth. Same thing with some Middle Eastern countries. Japan hearts the DS. In the Philippines? Nah.

Best of luck, Sony.
