* Carter to start new role Jan. 11
* Headed Boost during popular unlimited service launch
* Sprint shares down 2.4 percent on NYSE
NEW YORK, Dec 10 (Reuters) - Sprint Nextel S.N said on Thursday that Matt Carter, the former head of its Boost Mobile unit, would oversee the development of the No. 3 U.S. service provider's fourth-generation broadband wireless services.
Sprint is moving the executive to the new role after it put Virgin Mobile USA chief Dan Schulman in charge of Boost as well as Virgin, which it bought on Nov. 24. Both Virgin and Boost specialize in prepaid mobile services.
Carter, who becomes president for 4G services on Jan. 11, had headed Boost’s launch of a popular unlimited monthly service plan that has created strong subscriber growth since early this year. The popularity of the Boost service helped offset losses of monthly bill paying customers at Sprint.
In his new job, Carter will oversee everything from marketing, device selection and market launches for Sprint, which is offering 4G wireless services based on a network that Clearwire Corp CLWR.O is building.
Sprint owns roughly 55 percent of Clearwire and is depending on the venture, which also has cable and technology investors, for its next generation of wireless services.
Sprint shares fell 10 cents to $4.03 on the New York Stock Exchange at mid-afternoon.
