AT&T this morning announced its first-quarter 2012 earnings. The carrier sold a Q1 record 5.5 million smartphones -- 78 percent of them iPhones. That leaves 1.2 million Android and BlackBerry smartphones to make up the difference. AT&T didn't give a breakdown of non-iPhone sales, but it is worth noting that the heavily marketed Samsung Galaxy Note wasn't available until Feb. 19, so it missed half the quarter.

AT&T added 726,000 subscribers for the three months ending March 31, and saw its lowest churn in seven quarters.
