Sybase 365 Launches AvantGo for Symbian Smart Phones

Sybase 365, a subsidiary of Sybase, Inc. (NYSE:SY), the global leader in
mobile messaging services, today announced the launch of the AvantGo®
client for smartphones based on Symbian OSTM and S60. Symbian smartphone
users can now access updated, customized content from thousands of
mobile Websites anytime and anywhere – in
either an online or offline mode – in a format
that is optimized for the device.

Symbian develops and licenses Symbian OS, the market leading operating
system for smartphones, licensed by the world’s
leading mobile phone manufacturers. To date, more than 165 million
Symbian smartphones have shipped worldwide to over 250 mobile network
operators.

“With the rapid expansion and adoption of
mobile technology, users are beginning to expect more from their mobile
device,” said Marty Beard, president of Sybase
365. “We are dedicated to providing the best
in mobile content, and are pleased to expand on our relationship with
Symbian to enhance user experience and value.”

AvantGo for S60 on Symbian OS caches content locally, providing enhanced
navigation, faster browsing and dual online and offline availability. In
addition, AvantGo utilizes a patented advanced sync technology that
updates pages on the device, giving users access to the latest news and
information around the clock.

“S60 on Symbian OS was designed for ease of
use and functionality. AvantGo enhances our users’
experience by revolutionizing the way news is displayed on the device,”
said Jerry Panagrossi, vice president of U.S. Operations, Symbian. “Consumers
and professionals alike can now have access to diverse, timely and
customized information from market updates to entertainment.”

AvantGo provides media content partners and advertisers with a turnkey,
ad-funded mobile distribution solution –
without the cost of building an initial mobile audience or advertiser
network – and provides advertisers with reach
into a highly desirable mobile audience. As a result, hundreds of major
brands use AvantGo, which in turn provides mobile users access to both
quantity and quality of content.

“Mobility is the trend for the Internet and
advertising,” said David Wrieden, director of
online advertising for AccuWeather. “We are
able to connect with mobile users through our partnership with AvantGo,
and their reach is even wider now that the service extends to Symbian
smart phone users.”
