AT&T's Digital Life service is now available in 15 U.S. markets.

AT&T plans to begin trials for a number of different services, all of which are part of its "Digital Life" suite, this summer. The suite promises to allow customers to control aspects of their home or business - such as thermostats, door locks, garage doors, windows and lighting, and even to view video from a security camera - using a Web-enabled device, such as an iPhone or iPad.
