BARCELONA, Spain-- Openwave Systems Inc. (Nasdaq:OPWV), one of the world’s leading software innovators enabling revenue-generating personalized services which converge the mobile and broadband experience, today announced the Openwave Mobile Client Suite, a complete and integrated solution that leverages proven client products and several key product upgrades in user experience, browsing and messaging.

The Mobile Client Suite offers consumers, mobile operators and mobile device manufacturers a scalable and optimized solution across a wide range of platforms and market tiers. The suite includes the introduction of the Openwave Surfer browser, a full open internet browser with Web 2.0 functionality, and a new version of the Openwave MIDAS environment with advanced support for mobile widgets and mobile messaging. The Openwave Mobile Client suite is designed to help mobile operators and handset manufacturers build and deploy innovative products and services that drive the consumption of high-value personalized content and services.

“The first phase of the mobile Internet was largely driven by technology and access to services. At Openwave, we see the next phase driven by greater service adoption and usage, which will increase the overall value of mobile device products and afford operators a greater ability to monetize the mobile Internet experience,” said John Boden, senior vice president of product management, Openwave. “Openwave’s Mobile Client suite provides device suppliers the means to deliver innovative product designs and easily customize them for a diverse set of market and operator requirements with lower cost and risk. The client suite gives operators the ability to create and deliver ‘zero-click’ service delivery across devices and to leverage the idle screen for active content consumption.”
