several of mysterious manufacturer General Mobile's models, the DST3G candybar supports exactly twice as many SIM cards as your average handset. The whole dual SIM thing is kinda played out at this point, though, so what other ace can you pull out of your sleeve to separate yourself from the crowd? For the DST3G, that ace just happens to be support for UMTS 900 / 1800 / 1900 / 2100 (in addition to GSM with EDGE on 900 / 1800 / 1900), making it a world 3G traveler. Quadband 3G phones are rare enough as it is, but the dual SIM capability on top of that is just about unprecedented. Other goodies include a 2 megapixel camera, microSD slot, and QVGA display; look for it next month for a to-be-announced price.
