Who I have the same questioned this topic

Signal levels have degraded in Winston-Salem, NC to the point where my phone is not worth much more than a paper weight.  I have been with Verizon (and its predecessors) since 1987 and have never had this problem.  I've been a vocal customer, promoting Verizon over other carriers based on excellent signal quality.  I have not been able to maintain calls for the past 6 days, most notably in three distinct areas where I spend most of my time.  Any known issues in the area?
