"We believe PalmSource's strength as a leading mobile platform and wireless solutions provider will foster growth for the entire Palm Powered™ economy looking to capitalize on the burgeoning enterprise market," said David Nagel, president and CEO of PalmSource, Inc. "By delivering an enterprise-grade operating system and aligning with industry-leading partners such as IBM and RIM, PalmSource is further strengthening its leadership position in the enterprise market."

Launched earlier this year, Palm OS® Cobalt is designed to provide the foundation for next generation smart mobile devices by offering advanced enterprise-grade features including: multitasking and multithreading architecture; extensible communication and multimedia frameworks; robust system level security and a best-in-class development tool chain.

Announced at the Company's second annual Euro DevCon last month, PalmSource is making available to Palm OS software developers the email API that will be released with the first version of PalmSource™ Mail for BlackBerry Connect™. The email API is designed to enable developers to leverage the secure BlackBerry® email transport to create secure mobile data applications such as customer relationship management (CRM), sales force automation (SFA), supply chain management (SCM) and mobile field services for the enterprise environment on Palm Powered smartphones and wireless devices.

In addition, PalmSource is collaborating with IBM to provide Java technology for Palm OS and make it available to Palm OS licensees and software developers.

PalmSource is also working with IBM to enable JSR 75 for PDA integration and JSR 172 for Web services integration on Palm Powered mobile devices running the Java technology for Palm OS.
