It doesn't seem too useful at first glance, but imagine being able to text your mates with a simple "I'm here" to get your point across. Especially on a device with a numeric keypad, busting out an SMS with crossroads or landmarks can suck since predictive text systems aren't terribly skilled with proper nouns. Korea's KTF has launched what it calls "location-tracking MMS," allowing users to automatically attach zoomed in maps of their present location to outgoing multimedia messages. The carrier is also shopping around the feature for emergency use, since it's a quick and easy way for a subscriber to communicate their coordinates to rescue personnel (a la e911). With accuracy to within about 500 meters, though, you better deploy a big ol' group of rescuers.
