I think it's more likely that they haven't been on handsets that their target audience owns. They just added iPhone and Blackberry, and I can't name one of my friends who has a location-enabled smartphone that's neither a Blackberry nor an iPhone. For a while they were just on Boost, and don't know anyone who uses them as a carrier either. In any case I look forward to trying out the service with all of my friends who now can actually use it. Big congrats to the Loopt team, especially Sam and Alok who I know from school.
