Hate to say it but this sounds almost exactly the same as my experience in Arlington. I've had 2 dropped calls already today and average around 5 or so a week. I love the iphone features but as a phone (I can only speak for me) it is a gigantic fail.
Same here. I currently live in Clarendon and get pretty frequent dropped calls. I'm going to try the Edge thing while at home from now on since I go off WiFi for internet usage anyways.
