LG's pre-MWC revelations show no sign of abating, with the official unveiling of the device formerly codenamed "X3". The LG Optimus 4X HD is a beast both in and out and will no doubt be the company's major attraction at the trade show in Barcelona next week.

Packing a 4.7-inch True HD IPS (1280 X 720) touchscreen and a waistline of 8.9mm, the Optimus 4X HD is both mighty and svelte in equal measure, but it's the Nvidia Tegra 3 1.5GHz quad-core processor hiding in its bowels that will garner the most attention.

There's also 1GB LP DDR2 RAM on board, so if it doesn't zip along like a cheetah with a rocket strapped to its back we don't know what will. Although we suspect that there's a microSD card slot (the specs released don't say), 16GB of internal storage should be plenty to be getting on with.

Oh, and did we say that it'll come with Android 4.0 Ice Cream Sandwich straight from the box? No? Well, we have now...

The rear camera is 8-megapixel flavoured, while the front houses one of the 1.3-megapixel variety. And the 2,150 mAh battery promises "high battery efficiency". Intriguingly, there's also DLNA support on board for streaming shenanigans.

The best news, however, is that the LG Optimus 4X HD is coming to Europe first - and that means the UK. Ha, in your face Barack Obama, Lady Gaga and that kid off Star Trek: The Next Generation. It'll arrive in Q2, around spring time.
