The mysteries of ABC's "Lost" are about to get bigger -- and smaller.

The Emmy-winning hit is spawning a second series for mobile phones in a deal soon to close with a major U.S. carrier, sources said. About 20 episodes -- each several minutes long -- are being shot next month in Hawaii to hit phones sometime early next year.

The project is not being produced by ABC or Touchstone Television but is under the oversight of "Lost" executive producers Damon Lindelof and Carlton Cuse.
