New Sony Ericsson P900 is Unveiled at CTIA Show in Las Vegas 

Zi Corporation (Nasdaq: ZICA) (TSX: ZIC), a leading provider of intelligent interface solutions, today announced that its eZiTap Front End Processor (FEP) predictive text technology is now available for the new Sony Ericsson P900 Smart Phone, unveiled earlier this week at the Communications Telecom Industry Association (CTIA) industry tradeshow in Las Vegas. Zi's technology is accessible through Handango's e-commerce websites.

The P900 Smart Phone is the next generation model to the highly successful Sony Ericsson P800 product line. The handsets are sold through major wireless carriers around the world, such as AT&T Wireless, O2, Orange, TIM, T-Mobile and Vodafone. Along with the P900, the eZiTap FEP is also compatible with the existing line of P800 handsets.

Zi developed the eZiTap FEP product in close association with Sony Ericsson based on feedback from users who suggested there was a need for a word completion solution for the phone's virtual keyboard.

"We are very excited to see the high level of quality and innovation with which members of our Development Program keep creating useful and fun applications that evolve the use of our phones," said Mikael Nerde, Director of Sony Ericsson's Developer Program. "We are looking forward to more applications from Zi Corporation."

"Sony Ericsson collaborated with Zi because we have demonstrated our innovation and our responsiveness in developing interface technologies that increase the usability of devices and device applications for phone users," said Gary Mendel, VP of Sales and Marketing, Zi Corporation. "Powerful features such as Zi's unique word completion capability and learning functionality provide users with a quick and convenient way to tap in proper English words or texting lingo very quickly within any application throughout the smart phone."

Mendel noted that Zi's core business model continues to be based on embedded applications, but added that smart phone devices, which the industry expects to become the dominant handset on the world market, are being developed in a much more open system environment that allows users to download a wide variety of services. The P900 and all the Sony Ericsson smart phones use the Symbian OS (Operating System) and UIQ technologies, which are based on the new open system model.
