Well log my wife into the category of taking her Iphone 4 back. After approx 15 drop calls today and phone randomly dialing when talking (prox sensor Im guessing) she has had enough. What sucks is I have had approx 8 drop calls on mine today while our daughters 3gs (my old phone) has had zero. Her 3gs phone registers 5 bars and our has 1 at same locations. Just crazy. Im still holding out on returning, but I can't convince her otherwise. Kinda sucks since I stood in line most of the day to get two phones. However since she doesn't care for the feel and is having issues might as well return. I read where apple is coming out with a fix, but she feels this is just tricking the phone since our daughter has no issues at all. We are both apple fans so kinda hard to return any product.
