3Com, Psion to Join Hands on Software

3Com and Psion, the top two producers of hand-held computers, agreed to make their software compatible as they battle Microsoft in the budding market for wireless phones that can access the Internet. Psion already has backing for its software from the four biggest wireless phone makers through its Symbian venture. Nokia, the largest wireless phone maker, which already uses Psion’s software, became the first to license 3Com’s software to make a phone that will use a pen to input information, as 3Com’s Palm series does.
