AT&T (T - Free Analyst Report), one of the world's largest telecom service providers, posted strong results in the second quarter, sending its stock higher. Indeed, share net of $0.61 for the period (excluding a $0.07 one-time gain from a stock transaction) came in a nickel ahead of our estimate and a solid 13% above the year-earlier tally. The upside was driven by another impressive showing from the wireless division, which benefited from margin expansion, improved customer churn, solid data growth, the launch of Apple’s (AAPL) iPad tablet PC, and a record number of iPhone activations. (AT&T is the exclusive U.S. carrier for Apple's iPhone and iPad.) Additionally, cost-cutting initiatives and increased market penetration of U-verse, the company's new TV service, buoyed the bottom line.

Looking ahead, we expect the wireless unit (second only to Verizon’s (VZ - Free Analyst Report) counterpart in number of U.S. subscribers) to remain a major growth engine through the balance of this year and into 2011, as new handheld devices continue to hit the market, and as demand for mobile broadband services continues to surge. Consequently, even with the uncertain economic outlook, we are raising our 2010 and 2011 share-net calls by a dime each, to $2.40 and $2.55, respectively.
