The final versions of Opera Mini 5 and Opera Mobile 10, have today been released, and can be downloaded from any compatible phone by visiting http://m.opera.com/
Opera has been quite active on the Mobile browser front recently, especially with Opera Mini, which only recently has broken into two new platforms, Windows Mobile and Apple's iPhone OS. Although the Opera Mini browser is still in beta for Android and Windows Mobile, and the iPhone version is still not available.
Now the only platforms Opera Mini is yet to be available for are, Palm's webOS (although that might be underway) and Samsung's Bada. With this Opera's Presto web rendering engine is even more ubiquitous, second only to webkit.
Opera Mini 5 and Opera Mobile 10 bring a host of improvements in the mobile browsers, mainly in their support for tabbed browsing, a download manager, a password manager and a new speed dial with favorite websites. The latest version also brings support for Opera Turbo in Opera Mobile, which further increases speed of this powerful browser.
