Yes, it was Motorola who introduced the first dual-core smartphone but LG is now stealing the show by making the LG Optimus 2X White Edition available in South Korea. And it's not only Motorola that should worry about the arrival of Optimus 2X, Apple should also at least feel as if one of its toes is being stepped on-- LG has beaten the White iPhone 4 (which is rumored to be launched on February 27th) to the punch.
