Well, I know that the Samsung SCH-A970 can do this, but it is a CDMA phone for Verizon and it appears that you do not use Verizon. I am not sure of any other phones that have this feature, but since this Samsung can do it, I would assume that other high end Samsungs can do it as well, including GSM phones, but I could be wrong. Hopefully this will at least give you a place to start. Good luck
