Opera Mini

Recently Opera made Google™ the default search engine in Opera's mobile Web browsers. Now anyone using Opera Mobile or Opera Mini can access Google's powerful mobile search directly from the browser start page,this meaning you will be able to quickly and easily get the information they need, whenever and wherever they need it.
Opera Mini's ongoing success is a proof of the mobile Web's adoption by mainstream consumers. Because Opera Mini targets feature phones that have traditionally possessed limited browsing capabilities, millions of people have made the personal choice to download and install Opera Mini to their phones. These consumers tend to use the mobile Web more frequently and actively than consumers with more static, less dynamic mobile Web browsers. Every month, Opera Mini users browse more than 1.7 billion pages, with much of that traffic generated through the search function in the browser.
"Google and Opera have established a valuable relationship over the years and we look forward to continued collaboration on mobile products," said Jon von Tetzchner, CEO, Opera. "With 2008 poised to be the year the mobile Web goes mainstream, Google and Opera are extending this collaboration to give our users immediate access to the quality and convenience of Google's search results. We're excited to extend this productive relationship and we hope that the nearly 100 million people using our mobile products will agree."
