Sprint makes offer to buy rest of Clearwire Corp.
Sprint Nextel Corp., which is majority owner of Clearwire Corp., has offered to $2.1 billion to acquire the rest of the company in order to boost its own wireless data services.

While Clearwire has been looking for new financing, the company?s shareholders are not expected to accept Sprint?s offer.
