AT&T has come out with FamilyMap service for tracking AT&T signed-up phones from a distance. Any AT&T phone is supported by this and if you're looking to track a phone that doesn't have GPS / AGPS, then the Family Map Locator will rely on tower triangulation. Other neat things the Family Map Locator allows you to do is get location updates by setting up automatic emails or text messages, locate a swiped phone, and more. If you think you can use this Locator as a spy, then you're wrong. AT&T sends tracked phones text messages letting them know they've got someone on their tail. The first 30 days are free, then you're looking at $9.99 a month for up to two phones or $14.99 for up to five.
