I'm a little late to this thread, sorry...
AT&T m-mode models have had this kind of functionality for quite awhile.
"With a few keystrokes on a wireless phone, a m-mode subscriber is
given the approximate geographic location of his friend, such as a
street intersection. The two friends can then exchange messages, call
the other, or choose a place to meet from a directory of nearby
restaurants, bars, coffee shops, and bookstores."
I'm pretty sure they don't use GPS for this... I think they do some
form of triangulation from the cell towers.
