LG is going to unveil a 3D capable smartphone at this year's Mobile World Congress in Barcelona. Much like the Nintendo 3DS, the device won't require special glasses for 3D viewing and the South Korean electronics giant hopes to overcome the lack of content by creating its own ecosystem: the Optimus 3D will sport a dual-lens rear camera to record 3D photos and videos and has HDMI 1.4 and DLNA support baked in to stream content to other 3D-capable devices.

Apart from this not much is known in terms of specs, but earlier leaks suggest the smartphone will be powered by Nvidia's Tegra 2 SoC and carry a 4.3-inch (480x800 pixels) display, which the company introduced at CES. More details will be announced by LG next month, February 14, hopefully including pricing and a release date.

The Nintendo 3DS has proven that small-screen glasses-free 3D technology can work well – at least according to those who have gotten some hands on time with the upcoming gaming handheld. It remains to be seen if developers get on board with producing 3D content for smartphones or if this will remain just a wild gimmick.
