AT&T

AT&T released its Q4 2011 earnings this morning, saying it set sales records for Android devices in the three months ending Dec. 31. (It doubled Android sales in Q3 2011, you'll recall.) While it declined to give specific Android numbers, AT&T did say that it sold 9.4 million Android and iOS smartphones, 82 percent its postpaid sales were smartphones, and it activated 7.6 million iPhones. Do the math there, more or less, and you've got a boatload of iPhones, and some Android phones. But we're not one to look broken records in the mouth, and neither is AT&T, we reckon. The company also said it sold twice as many Android devices as it did in Q4 2010.
