I live in a small town w/ one cell tower. I've been using a variety of different cell phones and have never had any problems until the latest and greatest came along and screwed things up. Now, w/ the iPhone I miss perhaps 2-3 out of ten calls. I know I haven't left the calling area, no it's not on vibrate... etc. Am I alone with this problem or are others finding that the not so holy grail is missing calls?
