AT&T just helped themselves to a pretty nice second quarter, thanks, in part, to a growing Android lineup. How nice? Well, Ma Bell is reporting quarterly (Q2’11) revenue of $31.5 billion, a 2.2 percent year-on-year increase. AT&T sold 5.6 million smart phones, 2 million of which were Android-powered. Even though that figure seems low compared to the iPhone, it’s more than double what it was in the same quarter last year. Hey AT&T, do you see what happens when you release phones like the Atrix 4G? People buy them.

Hit the break to see a couple of bullet points lifted from AT&T’s press page.
