WHOA here, just a minute!!!
I am a Verizon customer (switched about 4 or 5 years ago) because AT&T frequently dropped my calls in downtown Atlanta, - forget suburban Atlanta. I frequently travel through Atlanta 'til today, in different directions, and I don't remember ever having lost a call with Verizon or ever having failed to secure a connection on my Verizon USB aircard, anywhere in the state of Georgia, - even while moving. (Perhaps personal hardware has as much to do with reception as provider infrastructure)
