I am thinking of doing this but have never had any other carrier but Verizon. I am having some conflicts with Motorola and Verizon and may bail. It seems like At&t may even have better coverage in my area. Has anyone ever been on At&t before? Does anyone know the data speeds I would receive on HSPA+ between Rochester and Syracuse, New York? Is their HSPA+ network dependable (I don't live in At&t LTE city).
