After AT&T announced plans to acquire T-Mobile USA for $39 billion last year, federal regulators blocked the deal, contending that it would reduce competition in the wireless U.S. market.

As evidence of that competition, they pointed in part to ads in which T-Mobile spokesmodel Carly Foulkes lampooned AT&T and Apple.

Not coincidentally, T-Mobile took a hiatus from those barbs while the deal was pending. But the acquisition is now off, and so are the gloves.

new T-Mobile ad posted online today features the new hot-rod Carly on her Ducati superbike, rocketing past a slower motorcycle, representing the speed of an iPhone 4S on AT&T.

It’s part of T-Mobile’s challenger strategy, attempting to win new customers with lower prices on devices and the promise of faster speeds. We’ll get a better sense for how T-Mobile USA is doing financially when its parent, Deutsche Telekom, reports quarterly earnings later this week.
