im an owner of the EVO4G and i live in an area where the service is "certified available" ( Bronx of New York City). my problem with this service is the fact that it isnt always stable as it should be. The 4G widget would be on, but the service bounces on and off, meaning it constantly is switching from 4G to 3G on its own, even when the widget is still on. this interrupts my entertainment drastically for the past 3 days straight. is there a reason why this is happening?
