Wireless service provider Helio launched a location-based service enabling subscribers to broadcast their whereabouts to select friends. The Los Angeles-based company also unveiled a $225 mobile phone
called Drift, which is required to access the service. The phone combines global positioning technology with Google's mapping service for mobile devices. "We're really looking at the social-networking
crowd," said a spokesperson. Helio service starts at $65 a month for 500 minutes and unlimited data services.
