I got Opera Mini 5 beta 2 working great on my 9700, and it seems a lot of the bugs have been fixed.
If you go to the thread located here, the answer is in post 2nd from the bottom on the first page.
I installed Version 4.3 to 4.7 and had no problem. I also used Desktop Manager to install and did not need BB Swiss Army Knife as stated in the thread.
Hope this helps. I tried Bolt during the day when I was having Opera issues and I quickly deleted it once I found this thread.
