Yeah, I would estimate my dropped call rate is around 20-30% (Northern Virginia) sometimes higher depending on the day. They said they built a new tower near me, but ever since I got that message, my coverage has dropped at least one to two bars everywhere I go.
Same here in Northern VA...this in addition to the 3.1 bugs is just maddening...enough to drive me to another carrier. Waiting on some Android phones to be released with VZW...Sprint has the the new HTC hero as well. Might be about the closest thing to an iPhone that won't drop my damn calls.
