It used to be that how a cell phone felt in your hand was a major reason to buy it. There simply weren't many other components to it, so the tactile sensation of the keypad, the cellular carrier or the flip-versus-"candy-bar"style were the only real choices.
In my opinion, forget those now-quaint reasons for purchase. If it doesn't feel right, hang up on it. After all, you'll probably use it several times a day.
