iPhonebook™ is launched on QUALCOMM's BREW® Platform

Wireless Service Puts Information Where Users Need It - On The Mobile Phone

San Jose, California -- March 3, 2003 -- Xpherix Corporation, the leader in personalized mobile connectivity, today announced iPhonebook™ based on QUALCOMM's Binary Runtime Environment for Wireless™ (BREW™) platform.

iPhonebook offers one-device wireless access to all personal address book contact information including phone numbers, addresses, e-mail addresses and the notes field, eliminating the need to carry electronic organizers, laptops or bulky address books. iPhonebook keeps this information up to date, ensuring connectivity in real-time.

The BREW platform is a thin applications environment for wireless devices. It provides application developers with an open, standard platform upon which to develop their products. Because the BREW platform is a standardized environment, it greatly simplifies the task of integrating applications onto wireless devices - from inexpensive, mass-market phones through high-end, multi-purpose wireless devices.

"Numerous analyst studies show that users' number one desired application for their mobile phone is one that makes it easier to make calls," said Nick Walker, Xpherix president and CEO. "QUALCOMM's BREW platform has made it possible to offer unique applications such as iPhonebook that make mobile phones truly convenient and productive tools."

"It is an exciting testament to the capabilities of the BREW platform that iPhonebook can deliver this kind of productive functionality to users," said Gina Lombardi, senior vice president of marketing and product management, QUALCOMM Internet Services. "The wireless carriers are also winners, in that iPhonebook offers them both data and voice revenue opportunities."

iPhonebook synchronizes with a user's existing address book - such as Microsoft Outlook® or Palm Desktop® - and makes that information available through the mobile phone. Users can launch iPhonebook on their mobile phone, search for a contact, view all the information they have on that contact and choose which number to dial - all within seconds. By providing anytime, anywhere access, iPhonebook helps users become more productive in their personal and professional lives.

Note to editors: CTIA has selected iPhonebook for inclusion in the Wireless Widgets Showcase which will take place March 18, in booth 4514, Hall E, at CTIA 2003 in New Orleans. iPhonebook may also be seen in the Qualcomm Partner Pavilion, booth 5331 and at Xpherix's booth 4013.
