Ok they aren't payphones... But they are call able telephones that are accessible by the public. They cool thing is that they do actually ring. This'll get the attention of anyone near to them. Even more so if anyone's looking at them. They are both iPhones, one is the 4G (left) the other is a 3G (right).
