Samsung's been blowing it up lately with dual-SIM versions of their Galaxy phones lately, but LG doesn't intend to let them get too far ahead. The LG Optimus Net Dual, which appears to be an updates version of the original Optimus S, is officially on sale in India for the equivalent of about $$210. The budget smartphone uses multiple GSM networks at a time and, surprisingly, appears to run Gingerbread. Dual-SIM devices are popular in developing countries, where cell networks can be few and far between and users often buy multiple pre-paid cards for more reliable coverage.
