Microsoft and British Telecommunications yesterday announced an expansion of their mobile Internet partnership. The two companies plan to use Microsoft’s Windows CE operating system to develop Internet-capable wireless devices. The duo intend to roll out consumer-multimedia services for mobile phones by this summer. Microsoft, which has been unable to equal 3Com’s Palm Computing unit in the handheld computing market, wants to use the partnership to sell its software to BT partner AT&T, a move that could help it better compete against its rivals. The partnership is one of many link-ups in the industry. Palm has recently reached separate agreements with Nokia and Symbian to develop mobile Internet phones. (Wall Street Journal 10/15/99)
