For those that like Opera Mini (I use it a lot!), they've just released v6.1 for BB. The install went smoothly, keeping all my bookmarks.
Among the new features, per the Opera forum
The text selection is greatly improved for touch screen devices. Just click on the text you want to select, then drag the handles to adjust the selection and press "Select".
Search faster! Search suggestions from Google and Yandex will appear when you start typing in the search field.
You can now search directly from the address bar! The search option will appear in the drop down list when you type something.
And fixes for the BlackBerry:
Fixed minor graphical glitches when opening text fields.
More robust virtual keyboard handling.
General bug fixes and improvements.
Known issue: search suggestions are only available if you have a socket connection (ie. if you are using WiFi or have entered APN settings for your device).
So far, no hitches or glitches. I'm running a BB 9550 on VZW, with OS v126.96.36.1992 (1754)
