Opera has a long-standing partnership with Nokia to provide a browser for its phones – it used to be Opera Mini on Series 40 nowadays it’s the full-fledged Opera Mobile on the Nokia X platform (Nokia’s premium WP platform is of course serviced by IE).
Opera will be the default browser on Nokia X phones, starting with the new Nokia X2, and it’s available for free download for current X owners.
Opera is now based on Blink – Google’s fork of WebKit – but adds Opera’s traditional strengths including Turbo (which compresses web pages before sending them to the phone) and Speed Dial (which pioneered the thumbnail bookmarks on the new tab page). There’s also the Discover features, which finds fresh content sorted by country and topic.
Opera is available for the regular Google-flavored Android, too.
