Today is officially the first day of Mobile World Congress and for our first stop on the show floor, we decided to hit up LG (great booth placement, right by the entrance). LG had a host of goodies to showcase, but the device we decided to spend the most time with was the company’s yet-to-be-released smartphone, the Optimus 3D. The new, Android 2.2 handset boasts a 4.3-inch, 3D screen that does not require glasses and, to be honest, looks quite nice. The device features a dedicated 3D button which will bring you to LG’s 3D-interface — giving you access to the camera and guide along with all the 3D content on the device. We could belabor you with more details, but a picture (and video) is worth 1,000 words, no? Hit the jump to check out a quick our clip and a gallery of the LG Optimus 3D.
