Does anyone know if you have to call TMobile to update them if you put the SIM in a new device? I got some cheap free phone and told them to put the smartphone plan since I would be using the N900 in the future and they did it. But the cheap phone was limited to 2G. When I first got the N900 the epc was internet2 but I switched it to epc. Though I'm not sure if I need to call TMobile to let them know to get the speeds reported. I'm usually in the DC area for school and work and the epc APN works.
