The run-up to 3GSM GSMA Mobile World Congress has begun with the announcement of LG's KF510 slider. Launching February 11th in Barcelona, the new 10.9-mm thin phone features a metal frame and tempered glass touch interface. LG primarily touts the phone's "advanced touch technology" (incorporating VibeTouch haptic feedback like their Voyager, we presume), 3 megapixel camera, and MP3 player. Available worldwide in March in Stardust Dark Gray or Sunset Red. How sweet.
