AT&T will update its "Rethink Possible" image campaign today with a nod toward new smartphone Nokia Lumia 900 by incorporating the phrase "It's what you do with what we do" into consumer advertising. The campaign will include TV spots as well as a major presence on social networks and blogs. "The real innovation that's happening is what people are doing, and how people are dealing, with technology ... the unique ways they use it to make their lives better," AT&T Senior Vice President Esther Lee said.
