For those of you that have use more than one GSM service provider at a time but hate carrying around more than one phone, the Samsung DouS is for you! This innovative phone allows you to use two SIM cards both at the same time, even from different providers. This great idea from Samsung has only been announced for Russia and is set to hit shelves next month retailing for 18000 rubles ($707CAN/$721USD). The only drawback to the phone is that you can expect not to get any discounts from carriers for signing a contact as it will be impossible for them to lock it down. Let hope we get to see DuoS over here in Canada and the United States
