Sprint signed David up for a two-year contract without permission after he transferred his service between a Motorola RAZR 2 and a Sanyo 8400.

David owned both phones when he made the transfer last month, long after his contract had expired.

Motorola has named Sanjay Jha as chief operating officer of Qualcomm to head its handset division, which is being prepared for a spin-off as a separate public company.

Motorola will split into two independent, publicly traded companies, the company announced Wednesday morning, splitting its troubled mobile-handset division from its profitable cable-equipment and enterprise-telecommunications-device business.

The billionaire investor said that he was suing Motorola to force it to hand over documents related to its mobile devices business.

Less than two years past the most successful stretch in its 80-year history, Motorola Inc. is considering a sale or spinoff its now free-falling cell phone business.
