The move by Yahoo coincides with a trend by other Internet media companies, including Microsoft, to establish access to Internet portal sites through mobile phones.
Portals are Web sites that compile a wide variety of content, services, and links to other sites.
Yahoo Mobile currently works with devices based on 3Com's PalmPilot as well as palm-size devices running Microsoft's Windows CE operating system, according to the company. The service is expected to work with other wireless devices by the end of the year. Future distribution agreements in the United Kingdom are expected soon.
