By Noel Randewich SAN FRANCISCO (Reuters) – Steve Mollenkopf, the new chief executive of Qualcomm, said on Tuesday that the mobile chipmaker is developing technologies that will drive continued demand for smartphones even as others worry that the smartphone markets best days are behind it. Mollenkopf, 45, who was previously chief operating officer, officially took over as chief executive officer at the companys annual shareholders meeting on Tuesday. He was named in December to replace Paul Jacobs, the son of a Qualcomm co-founder. A lot of people talk about the fact that everyone has a smartphone.
