Why Sony chose to sit on this one, we have no idea, but the company just revealed that its software update for the 2011 lineup of Xperia phones -- which was released last month -- also adds browser support for WebGL. This means that if you're holding an Xperia Arc, Mini, Neo, Play, Ray... or any other of its most recent handsets, then there's a good chance you're wielding one of the first Android phones to support this modern graphics platform. Designed to bring advanced visuals and gaming to the web, the API holds roots in JavaScript and has been used to develop everything from Angry Birds to far-out music videos. Sony Ericsson first previewed its WebGL efforts back in February, and after all these months, its official arrival is a welcome one, indeed. For a quick demo video, be sure to hop the break.
