The LG Optimus 2X -- also known as the Optimus Star -- is the world's first dual-core phone, and packs an Nvidia Tegra 2 processor to power its Android brains.

The Tegra 2 runs at 1GHz, but LG promises Web browsing and gaming will be faster than with a single-core 1GHz processor -- such as Snapdragon or Hummingbird -- thanks to its two cores. But despite being such a powerhouse, its real advantage could be the power-sipping battery life. 

The Optimus 2X has a 4-inch screen with 480x800-pixel resolution, 8GB of storage and support for sticking up to 32GB more in its microSD memory-card slot. 

The phone supports 1080p HD playback, but we don't see an HDMI port on it, so you'll have to use DLNA to connect wirelessly to your HD telly. It's also possible LG has sorted out a cable that converts from micro-USB to HDMI, like Samsung did for the Galaxy S.

If you prefer to film your own movies rather than watch someone else's, the Optimus 2X has an 8-megapixel camera on the back and a 1.3-megapixel front-facing camera for when you're ready for your close-up.

The Optimus 2X will sport Android 2.2 Froyo, despite the fact that the latest version, 2.3 Gingerbread, has already arrived on the Google Nexus S. But don't panic, because LG promises it will be updated at some point, and we don't think Gingerbread has any crucial, life-changing features anyway.

LG hasn't made much of a splash in smart phones lately, although we do adore the LG Optimus One for being so mindbendlingly cheap. The Optimus 2X, with its dual-core processor, could change all that, but we're left with one question -- why didn't LG name it the Optimus Prime?

The Optimus 2X is coming to Korea next month, and LG says we won't be far behind. Click through the images above to see more sides of the Optimus 2X.
