AT&T

We've long cast a wary eye toward AT&T when it comes to Android (and rightfull so, between an initially tepid adoption rate, suspect devices (and devices), an odd apps policy and the whole faux-G thing. But there's no denying this: Sales of Android smartphones more than doubled on the U.S. carrier in the third quarter of 2012 2011 when compared to Q3 a year ago.

AT&T didn't give specific numbers, but it did say that non-iPhone devices (Android, Windows Phone and BlackBerry) made up almost half of its 4.8 million smartphone sales for the quarter. By comparison, AT&T activated 2.7 million iPhones in Q3. Some 52.6 percent of AT&T's 68.6 million postpad subscribers have smartphones.

AT&T also saw an increase of 2.1 million subscribers, to surpass 100 million total. Its stable currently includes the Samsung Galaxy S II, Motorola Atrix, Samsung Infuse, HTC Inspire 4G, Samsung Captivate and Sony Ericsson Xperia Play, among others.
