The last three months of 2010 marked the last quarter that AT&T had the iPhone all to itself, and the carrier got the most it could out of it: It activated 4.1 million more iPhones.
As Dan Frommer notes, that’s down one million from Q3 of last year, but it’s still AT&T’s second-best iPhone quarter ever. Overall, the carrier added a record 2.8 million more wireless customers.
This quarter, of course, is the quarter that AT&T’s U.S. exclusivity for the iPhone goes away, courtesy of Verizon.
AT&T also said it activated 442,000 wireless plans for tablets. That number includes both the iPad and Samsung’s new Galaxy Tabs running Google’s Android; reasonable to assume that the overwhelming majority of those activations are for Apple’s machines.
