After a little over three years, Apple's iPhone continues to prop up AT&T's wireless business, at least in part. Out of the 8 million smartphones AT&T said it activated in the third quarter, more than half -- 5.2 million -- were iPhones.
AT&T announced the numbers as part of its third quarter earnings, in which the wireless carrier posted "record wireless sales." In addition to 8 million smartphones, AT&T said it added 2.6 million wireless subscribers, "the highest third-quarter net gain in the company's history," and now claims 92.8 million subscribers overall.
With Apple's iPhone playing such an important role in AT&T's wireless business, it will be interesting to see how the company fares should the iPhone make its rumored trek to Verizon in 2011.
