LG has, in the most casual fashion possible, revealed the name of a new smartphone it intends to launch in the Korean market: the Optimus 2X. That brand name was buried deep in a release yesterday about exclusive Ennio Morricone content bundled with the Optimus Mach, though some studious folks have unearthed it and subsequently found YouTube content showing off the handset. Codenamed the SU660, the 2X looks almost identical to the LG Star we handled for ourselves recently, with the only differences being in product code (the Star was dubbed P990) and the button array at the bottom. Looking at the videos after the break, most of the onboard content bears LG's local branding of Cyon, leading us to suspect the 660 is just the Korean variant of the Star. Either way, that LG presser also notes that the Optimus 2X should be launching within the next couple of months -- just in time to take the Nexus S down a notch or two, eh LG?
