LG KS660 seems to hit the market of China, Korea, Russia and its several satellites. As for the US market, the manufacturer is not thinking about it yet. Americans are upset about it, and hope that LG will change their decision and release the phone to the international market.
The fact that KS660 is given so much attention can be explained not only by dual SIM support, but also by a 5 MP camera with autofocus and flash, 3” WQVGA display, and a stylus.
