Mobile Diagnostix to Deliver Superior Customer Care to the Wireless Industry

CTIA WIRELESS, ATLANTA, March 22, 2004 — Mobile Diagnostix Inc. (www.mobilediagnostix.com), a pioneer in lowering customer care expenses for wireless carriers worldwide, announced today it has joined the Palm Powered™ Mobile World program as a charter member.

Palm Powered Mobile World is a PalmSource marketing initiative that connects mobile operators, infrastructure and middleware partners and software developers in the wireless Palm Powered economy. PalmSource®, Inc. (NASDAQ:PSRC) is the provider of Palm OS®, a leading operating system powering next generation mobile devices and smartphones. The Palm Powered Mobile World is designed to bring Palm OS software applications and solutions to market, provide increased revenue opportunities for partners and deliver a superior experience for users of Palm Powered smartphones.

Mobile Diagnostix's patent-pending Mobile Care Framework automates the customer care process reducing the challenges faced by customer care representatives supporting next generation mobile handsets. Through automated handset analysis the system detects configuration errors, system parameters and known application conflicts and provides the corresponding resolution. The advanced framework supports a variety of operating systems for smart mobile devices, including the industry-leading Palm OS.

"We are pleased to welcome Mobile Diagnostix as a charter member in the Palm Powered Mobile World program," said Albert Chu, vice president of business development at PalmSource, Inc. "We believe the Mobile Diagnostix advanced customer care solution will further our goal for Palm Powered smartphones to have one of the lowest support cost for mobile operators to deploy."

"The large number and wide variety of Palm OS applications available to users of Palm Powered smartphones is a major advantage of the Palm OS platform," said Mobile Diagnostix CEO Ian Collins. "Our relationship with PalmSource will allow us to assure mobile operators that they will be able to provide the best customer service in the industry, at the lowest cost, to all of their subscribers who choose Palm Powered devices."

Research shows that customer satisfaction is key to driving usage and adoption of new wireless products. Satisfied mobile data subscribers use more data, are less likely to move to another network, and provide positive endorsements to friends, family and colleagues. Quick effective customer care is critical to increasing customer satisfaction during the rollout and maturation of mobile data product portfolios. The carrier/subscriber relationship enhanced by high quality customer care is one of the keys to building long-term profits.
