Sun Announces Broad Release of UTI Digital Certificate Through Java Verified Program to Help Drive Worldwide Mobile Application Security

Unified Testing Initiative Helps to Reduce Cost and Complexity for Developers, Ensure Quality of Applications and Enhance Security For Mobile Networks and Devices.

SAN FRANCISCO, Calif.- Sun Microsystems, Inc. (NASDAQ: SUNW), today announced wider access to the Unified Testing Initiative (UTI) digital security certificate for installation in Java technology-based mobile and embedded handsets. With the release of this digital security certificate, non-UTI member companies will now be able to run Java Verified signed applications on their mobile phones. As a result, more end users will benefit from the availability of consumer friendly, quality-tested, traceable content from third party developers.

In addition to the security aspects, signing applications with the UTI certificate greatly enhances the consumer experience by providing easier access to identified third party access rights with fewer prompts. Sun also announced that new Unified Testing Criteria (UTC) Version 2.2, the application testing criteria for the Java Platform Micro Edition (Java ME), developed by UTI member companies, is now under review and planned for release in July 2007. Both of these efforts are part of a greater UTI goal to facilitate the growth of the mobile application market by consolidating individual company testing programs, minimizing complexity for the developer and reducing overall application deployment costs and time to market.

“The Java Verified Program is an important market enabler for world wide distribution of mobile content. Industry adoption of a common security certificate will help provide a better overall end user experience and ensure greater security for mobile applications across a broad range of devices,” said Laurie Tolson, vice president of the Client Software Group at Sun.

Under the UTI’s direction, Sun Microsystems operates the Java Verified Program, which helps enable developers, manufacturers and wireless operators to confidently create, deliver and monetize mobile content and services. All applications which pass the Java Verified Program are signed with the Java Verified Digital Signature and are eligible to promote their applications using the widely recognized Java Powered logo. They may also participate in the powerful Java technology branding program (among the top ten most recognized technology brands) and partnerships, including promotion on java.com.

The UTI is an open industry initiative consisting of LG Electronics, Motorola, Nokia, Orange/FranceTelecom, Samsung, Sun Microsystems, Sony Ericsson and Vodafone that creates testing criteria to address application deployment challenges and facilitate greater network security. Companies who participate in the UTI reduce their internal testing costs and ensure their testing requirements are addressed in the Java Verified Program, the only industry developed and supported application testing and signing program. The Unified Testing Criteria focuses on several areas including how well an application behaves on a mobile device and basic usability of the application.

Since its launch in early 2004, over 13,000 applications from more than 3,100 registered developers have been tested through the Java Verified Program and the number of developers and companies leveraging the program continues to grow. In addition, the program supports approximately 400 Java technology powered handsets - more devices than any other mobile application testing program, including all of the major global manufacturers.
