Opera announced that it has made Google the default search engine for its mobile browsers, Opera Mobile and Opera Mini. From now on, mobile users that work with Opera can access Google's search engine directly from the browser's start page, for a quick and easy way to get the information they need.

The new mobile collaboration between Opera and Google covers all global territories except Russia and the Commonwealth of Independent States (no idea why is that), and includes all of Opera's standard mobile browsers.

Opera might have chosen the G-search-engine over Yahoo (which was made the default search engine on Opera's mobile browsers a year ago) following countless complaints from consumers who were unhappy they couldn't make Google the default browser page. Moreover, Google has been the default search option on Opera's desktop browser for many years, so it's somehow natural that it now became the default for mobile browsers too.

"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."

Opera Mini and Opera Mobile are the most popular mobile browsers in the world, being used on more than 100 million handsets. Opera Mini users, for example, browse more than 1.7 billion pages monthly. Both Opera's mobile browsers offer advanced features, specially adjusted for cell phones, including Opera Zoom, Opera Link and Speed Dial.

While Google recently introduced a new and improved search engine for mobile phones, Yahoo doesn't seem to care too much about the mobile side of the Web. Should we say "too bad", or should we be happy that Google won another pseudo-battle with Yahoo?
