By Lucas van Grinsven

AMSTERDAM (Reuters) - Mobile phone maker Sendo has filed a suit in a U.S. federal court against its former partner Microsoft, accusing it of stealing its technology and customers.

The small British company was Microsoft's key partner in entering the 400 million unit a year mobile phone market until the two companies unexpectedly cut ties last month without disclosing all the reasons why they fell out.
