Opera Software has thrown open the doors to reveal the final version of its popular Opera Mini 4.2 browser for mobile phones. The 4.2 version has been in beta the last few weeks, and now that Opera Software has opened a new server park, users of the browser in the United States should see a 30 percent speed boost. This release is the first version officially available for Google’s Android mobile platform — and the T-Mobile G1 smartphone. It’s also the first Web browser alternative to the built-in browser on the open Android platform.
