“Over the coming weeks, AT&T is rolling out cellphone location tracking that’s designed to route emergency calls to 911 more quickly. The company says the new feature will be nationwide by the end of June and should make it easier for, say, an ambulance to reach someone experiencing a medical emergency. At first glance, it seems like a no-brainer. But it’s also a reminder that as phone companies promise to save lives, they’re also using a lot more data about you in the process.”
