AT&T and T-Mobile rocked the United States this morning with merger plans that would make T-Mobile USA part of AT&T's empire. (That's assuming the buyout receives regulatory approval; until then, it's business as usual at T-Mobile for now.)

Both T-Mobile and AT&T have a claim to fame in recent smartphone history. AT&T was first to get the Apple iPhone, in an exclusive two-year deal no less, but it was T-Mobile that first got the Android ball rolling with the T-Mobile G1.

CNET will have much more news and analysis coming up. In the meantime, here's a look at the two companies by some key stats, including current coverage maps for voice and 3G data.
