AT&T (NYSE:T), the country's largest telephone company, is not typically known for being nimble. John Donovan, the company's senior executive vice president of technology and networks, has been on a mission to change that over the past few years. Although not unique among wireless companies or vendors, AT&T's technology council has been the focal point of its efforts to drive innovation, new ideas and new ways of thinking within the company. The technology council is behind AT&T's "foundries" and innovation centers around the country and across the globe, and has helped change the culture within AT&T. CNET takes an in-depth look at the council, Donovan's work and how AT&T is changing. Article
