Everyone wants to phight the iPhone, and now Sony is getting into the mix with help from it’s Sony-Ericsson partnership. Already pimping phones under the Walkman label, there’s been much speculation that a PSP-based phone was in the works, and now Sony-Ericsson has a patent for a video game-centric phone that has very PSP-looking buttons.

The touchscreen-based phone also has accelerometer support like the iPhone, as well as a vibrating, or “rumble”, feature.

This is the most concrete evidence yet that such a phone in in the works, and we wouldn’t be surprised if it had an Xmas 2008 launch.
