Following its competitors
down the path of familial omniscience, AT&T has rolled out its aptly-named FamilyMap service for tracking signed-up phones from afar. Interestingly, any AT&T phone is supported -- if you're looking to track one that doesn't have GPS / AGPS, it simply falls back to less-accurate techniques like tower triangulation, which is better than nothing. Besides simply scouting your kiddies (or spouse, or whomever else agrees to your oversight) on a map, you can do cooler things like set up automatic emails or text messages to get location updates, track a swiped phone, and more. Sadly, your ability to spy is limited by the fact that AT&T periodically sends tracked phones text messages reminding them they've got Big Brother on their tail, but it's better than nothing. The first 30 days are free to try, then you're looking at $9.99 a month for up to two phones or $14.99 for up to five.
