Sprint is considering a spinoff of its WiMax division, combining it with wireless startup Clearwire, to form a venture with national reach in wireless spectrum. Forming a new company to focus on WiMax would allow backers to bet on it, but keep the huge capital expenditures required from a national rollout off Sprint's books. The cell provider is hunting for a new CEO to replace ousted exec Gary Forsee and is looking to staunch its bleeding of customers. [WSJ]
