SAN JOSE, Calif. (AP)--Dell Computer Corp. and Good Technology Inc. will work together on designing a new wireless handheld for corporate customers, the companies announced.

The Dell-branded product, expected to be completed next year, would run Good's wireless messaging system.

Meanwhile, Dell, which began selling its own Microsoft Pocket PC-based handhelds in November, said Tuesday that it would begin selling Good's G100 wireless messaging device.

Demand from Dell customers to provide Good's device and wireless messaging service led to the deal, said Tony Banadero, a marketing director at Dell.

The alliance with the Round Rock, Texas-based computer giant marks a significant coup for Good, a Sunnyvale-based startup competing with Research in Motion, maker of the BlackBerry e-mail pagers.

The messaging device market has been sluggish, hovering at roughly 500,000 users, but with Dell expanding into that arena, perhaps that will soon change, said Danny Shader, president and CEO of Good.

The marketing and technology deal is not exclusive, Banadero said. Dell, which already sells RIM BlackBerry devices, could choose to work with RIM on a new product as well, he said.
