Softbank Corp.'s $21.6 billion bid for mobile carrier Sprint Nextel Corp. won approval from the last U.S. regulatory body reviewing the transaction, according to sources.
All three members of the Federal Communications Commission have voted for the deal, said the sources, who asked not to be identified because the matter hasn't been made public.
The approval also covers Sprint's offer to buy the half of wireless operator Clearwire Corp. it doesn't already own, they said.
