I just downloaded Opera Mini 5 beta for my Nokia 5800 XpressMusic. This new version of Opera Mini offers many new features like Speed Dial, Tabbed browsing, Password Manager, and much more. I think, “Tabbed browsing” feature is a super feature — with other new features, of course. If you want to download, you can go directly to m.opera.com/next/ from your phone web browser, or download it to computer first. Anyway, I still keep my Opera Mini 4 installed. So far, I’m happy with this new Opera Mini 5!
Here are some screenshots (click to enlarge):
