I am going crazy because a co-worker bought the G2X and while we are in the same office, he is getting 3G/4G data speeds while my MT4G switches between Edge and 3G. He is getting 6M down and 3Mg up while I am only getting 0.1 down and 0.17 up. Does anyone know why this is so? We are both on TMO network it just doesn't make sense. I call TMO and they said they will troubleshoot the area.
