It’s out of beta, it’s free, and it’s here. Opera Mini 4 works on Java-enabled phones and includes “native Blackberry menus,” faster page rendering, Landscape Mode, and a cool feature that allows you “to synch your Bookmarks and Speed Dial with those on your Computer” via Opera Link.
There’s also a virtual mouse feature which gives you a tiny mouse cursor that you can use to scroll around and click things as well as Opera’s Small Screen Rendering feature that helps alleviate having to scroll horizontally by “adjust[ing] the page structure on the fly.”

Is it me or Opera Mini and Beta did not work well on Treo 700P and 755P. I have IBM Java installed on my phones but a lot of time, Opera Mini could not get thru the loading page. It is sometimes frozen and I had to do soft reset :-( Opera Mini Beta is nice with little mouse cursor, let u surf like on desktop.
