AT&T's numbers are up, and they're good: $31.4 billion in the fourth quarter of 2010, $653 million more than Q4 the previous year. 4.1 million iPhones and 442,000 tablets were put online by the company that quarter, helping to drive 2.8 million new wireless subscribers, 95.5 million total, and a boost in revenue per subscriber of 2.2 percent. That's $62.88 average per month per subscriber -- maybe ditching unlimited data is paying off. Additionally, the company posted its best ever Q4 wireless churn (subscribers switching carriers) of just 1.32 percent (1.15 percent postpaid), but we're thinking the launch of a certain smartphone on a certain competitor could possibly have that number increasing ever so slightly this quarter. We'll circle back in three months and see where things stand.
