AT&T Mobility (NYSE:T) CMO David Christopher has a lot on his plate. He's not just in charge of AT&T's wireless marketing and promotions but also plays a key role in the company's developer community and was front-and-center at AT&T's annual Developer Summit, which took place earlier this month in Las Vegas. Christopher spoke with FierceDeveloper Editor in Chief Sue Marek about the company's latest marketing push that goes after T-Mobile US ( NYSE:TMUS) and Verizon Wireless (NYSE:VZ) and how developers can benefit from some of the latest AT&T initiatives such as Sponsored Data--where partners can subsidize consumer data so that it doesn't count toward their data bucket. He also spoke about the wearables market and opportunities for developers there. Hot Seat
