BARCELONA, Spain--LG offered an early peek at its new smartphones on the day before Mobile World Congress began. Though each handset was impressive in its own right, the 4X HD is arguably the most noteworthy of the pack. Not only does it come with Android Ice Cream Sandwich, but it's also powered by a 1.5GHz quad-core processor. The candy bar design is pretty standard, though you can't miss the sharp 4.7-inch HD display. It offered great color resolution and slick graphics and animation.
