Virgin Mobile Chooses InfoSpace for World's Most Comprehensive Mobile Search

InfoSpace, Inc. (Nasdaq:INSP), a leading developer of mobile
technologies, will today announce that it is supplying Virgin Mobile
with its complete suite of mobile platform services, including the
addition of a customized, integrated mobile search solution. As a
result, Virgin Mobile will be able to offer its subscribers the
ability to search the web, WAP sites and Virgin Mobile's own portal
and storefront providing access to ringtones, games and other premium
content.

InfoSpace's next generation mobile search solution for Virgin
Mobile will reflect the company's recent partnerships with FAST Search
& Transfer, a leading developer of search technologies, and InfoGin, a
leader in the field of Web-to-mobile content adaptation. Virgin Mobile
will benefit from FAST's superior search software, relevancy
algorithms, crawling and indexing technologies and InfoGin's
Web-to-mobile content adaptation technology to deliver the most
comprehensive and commercially deployed mobile search solution.
InfoSpace's industry-leading metasearch technology seamlessly blends
results from several sources including Storefronts, WAP and Web
indexing, as well as Portal Search. With the InfoSpace's mobile search
solution, operators can maintain visibility while providing users the
advantages of a comprehensive mobile search experience that enables
searching for any content or information, regardless of its origin or
format, using a single search box.

Nick White, Head of Digital Services and NPD at Virgin Mobile,
said: "If the impact of the internet on our daily lives, as well as
the global economy, has taught the mobile world anything, it is that
it's no longer about searching for the next killer application --
search itself is the killer application. Virgin mobile is a firm
believer that the there should be no limit to the content available
for our users -- from the latest celeb gossip to searches for
entertainment in the local area or even the most cryptic piece of
trivia -- it must be available to everyone, everywhere. We are very
pleased to extend our relationship with InfoSpace into this exciting
new area."

George Fraser, Managing Director - Europe, InfoSpace Mobile, said:
"The mobile phone has revolutionized communication when on the move.
Mobile search is the next stage of this revolution and brings all of
the world's knowledge to mobile users' fingertips. We have been
working with Virgin Mobile on mobile content since 2001, so we know
what their subscribers expect and demand. Our intimate understanding
of the mobile portal, combined with our heritage in online search and
directories, means we are uniquely placed to enable operators to
really exploit the potential of mobile search."

InfoSpace already provides mobile search services for numerous
operators worldwide including Sprint in North America, which included
the world's first cellular location-based search service.
