It's already a tad late but let me present TechPinas' Video Review of LG Arena KM900's S-Class 3D User Interface:
It's a good phone really. The form factor is really solid and the UI is spectacular.
11.5mm thick, KM900 boasts of a high-res 3-inch 800x480 display, 5-megapixel camera (and a secondary one in front for video calls), built-in GPS, WiFi, and an "innovative S-Class 3D interface."
LG Arena is now out in the Philippines and is retailing for Php24,990 . It comes in Silver, Titan Black and Dusty Pink. *thumbs up*
