We'll have to wait just a bit to see Apple's own quarterly results on Tuesday afternoon, but there's plenty to look forward to if AT&T's own Q2 2012 results are any indication, with the onetime exclusive carrier activating 3.7 million iPhones during the quarter.

AT&T has announced the results of its 2012 second quarter, and there's plenty of happy dancing around Ma Bell headquarters on Tuesday. Overall quarterly revenue for the company came in at $31.6 billion, with the wireless division showing a 4.6 percent increase to $16.4 billion all on its own.

All told, the carrier made a handsome $3.9 billion profit during the second quarter, a 10 percent growth in earnings in what the company calls its "best-ever postpaid, prepaid and total wireless churn" quarter.

Beating analyst expectations of only 230,000, AT&T increased its lucrative postpaid subscribers by 320,000 -- but that's still a far cry from what rival Verizon Wireless managed to announce last week with 888,000 new subscribers.

On the smartphone front, AT&T activated 5.1 million handsets in Q2, and not surprisingly, most of them were still iPhones -- 3.7 million, in fact, and 22 percent of those came to the company from rival carriers or were first-time owners. 62 percent of its postpaid customers are now smartphone users, an increase of 50 percent during the same quarter last year.

Notably, AT&T saw revenue from its wireless division increase even more than Verizon, to $6.4 billion -- an 18.8 percent increase from last year. "Branded computing" -- which includes tablets and mobile hotspot plans -- added just shy of half a million new customers for a total of 6.3 million, a whopping 50 percent increase over Q2 2011.

The rest of AT&T's products were largely just holding on, with the company's U-verse division showing a slight blip with 6.8 million subscribers, almost all of which had internet (6.5 million), while only 4.1 million were taking advantage of the TV service.
