Business Wire, July 8, 1997

REDWOOD SHORES, Calif.--(BUSINESS WIRE)--July 8, 1997--Unwired Planet, Inc. (UP), today announced UP.Link Platform(TM) 2.0 and the immediate availability of the HDML (Handheld Device Markup Language) Software Developer's Kit (UP.SDK(TM) on www.uplanet.com.(R) The free UP.SDK allows developers to quickly create interactive applications and content for a new generation of smartphones, such as those available for AT&T(R)Wireless PocketNet(TM) service, Bell Atlantic(R) NYNEX(R) Mobile Cellscape (SM)service, and GTE Wireless(R) SuperPhone service. The UP.SDK supports HDML 2.0 as submitted by Unwired Planet(TM) to the World Wide Web Consortium (W3C). With the UP.SDK, developers can enrich current Internet- and intranet-based applications and corporate client/server database applications with live access from the screens and keypads of smartphones.

"Developing with HDML 2.0 is free and open for any Web site," said Benjamin Linder, vice president of marketing, Unwired Planet. "We've made it easy for content providers to extend their Web sites, providing access to millions of mobile phone users worldwide. With HDML 2.0, sites can expand reach, leverage existing resources and increase revenue potential."

A unique capability of UP.Link(TM) Platform 2.0, which is supported by the UP.SDK, is the ability to "push" information to mobile phones enabled with UP.Browser.(TM) Any Internet or intranet Web server can transmit urgent alerts that notify the user of specific events.

These events may be the arrival of an Email message, a change in a stock's price, low inventory levels, late flight departures, or any other conditions selected by the user. This revolutionary capability brings the innovative Web "push" model to the pockets of mobile phone users.

"Syclo's growing base of Microsoft Exchange users, and soon Lotus Notes and Novell Groupwise users as well, can now manage calendars, contacts and Emails, all from their mobile phones. With UP.Link Platform 2.0 notification support, the Syclo Information Manager proactively alerts users to just the critical information they need as it becomes available," said Richard Padula, president, Syclo Corporation. "Unwired Planet has allowed us to implement a cutting-edge wireless strategy with minimal development effort that dramatically increases productivity for our users."

"Unwired Planet's 2.0 release allows Realogic's mobile customers to send and receive real-time information to and from their corporate databases or intranet," said Gary McGuire, director, wireless practice, Realogic, Inc. "The notification and built-in fax support, plus advanced security features of 2.0 will make mobile phones more useful and pervasive than ever before."

HDML-based interactive applications and services can be deployed rapidly using existing Internet content, authoring tools and programming skills. Web site information is merely formatted using HDML to make the information visible to mobile phones running UP.Browser. Web development tools vendors are quickly adding support for HDML 2.0 to their tools.

"HDML 2.0's native, URL-based navigation model allows our developers to seamlessly deploy Web database applications to desktops and smartphones," said Jeremy Allaire, director of technology strategy for Allaire(TM) Corp. "Combined with Cold Fusion(R)'s integration of Internet messaging protocols and directory standards, developers will be able to deliver incredibly rich, interactive network applications to HDML 2.0 compliant devices."

The HDML 2.0 UP.SDK is immediately available for download, free of charge, at http://www.uplanet.com(R) and includes a set of sophisticated tools to simplify development:

-- Smartphone Simulator-An NT/Windows95 simulator of an HDML- enabled smart-phone. Allows rapid development and testing of applications without the need for a physical phone. Enables developers to model and debug HDML content and applications. Simulates various phone models, each with different keypads and display characteristics.

-- Alerts Manager-Enables Web servers to "push" URL's and their content to mobile phones running the UP.Browser.
