It's just over a month before Mobile World Congress 2012 kicks off, and the smartphone rumour mill is in overdrive, with the latest leak suggesting LG will be among the first to unveil a quad-core smartphone at the expo.

The new phone, currently known as the X3, will apparently ship with the new Nvidia Tegra 3 quad-core processor under the glass, and a 1280x720 resolution, 4.7-inch display. The Pocketnow blog has a pic, showing a slimmed down version of last year's Optimus 2X, which includes LG's standard trio of hardware navigation controls despite the X3 apparently running on the Ice Cream Sandwich version of Android — software that includes the same controls in virtual on-screen buttons.

The same rumours are also suggesting LG will include a 2000mAh battery with the X3, which would be a big step up from the 1500mAh battery pack in the Optimus 2X. In conjunction with the power efficiency promised by Nvidia in regards to the Tegra 3 chipset, the X3 could be a phone that runs all day long.

Mobile World Congress will run from 27 February to 1 March this year, so we'll have to wait until then to see how accurate this information turns out to be.
