Think Americans have a love affair with their cell phones?  Move over, friend, because South Korea has us beat.  In a country with 48.8 million people, South Korea's Communications Commission reports that there are over 50 million cell phones in use.  This means, theoretically, that there are some 1.2 million people wandering around with at least two phones, but if you factor in young children and people without a cell phone, the number is greater.  Just like in some Arab nations and Japan, many people have more than one cell phone on their person.  Each phone is set with different ring tones so the owner can tell right away if the call is from a family member or a business associate.
