Does anyone know if a Rogers locked Nokia Lumia 900 or 920 will work on the AT&T network in the U.S.? I thought that those 2 networks and the frequencies they use, are largely compatible. If that is the case, can I use my phone with a Straight Talk AT&T Compatible SIM in the U.S., without unlocking the phone? I figured that someone on here may have tried this, or know someone who was maybe successful in doing this. Thanks.
