Dual-sim phones aren’t usually held in high regard – and are usually relegated to secondary phone duty. So it was kind of surprising to learn that Samsung recently introduced the Galaxy S2 Duos dual-sim Android smartphone in China. The phone supports both CDMA and GSM, and is equipped with a dual-core 1.2GHz processor, 4.52-inch Super AMOLED+ display, 8-megapixel camera and a beefy, 1800mAh battery to compensate for the dual radios. Want one? Too bad – it seems like this particular device will be only available in China.
