http://forum.xda-developers.com/show...5&postcount=30 that thread has a shortcut in it. They also have some other files for Opera Mini 5 Beta if you keep reading.
I still prefer Opera Mini 4.2. It's just faster and the new one seems too much like Opera Mobile (and I can load that anytime I want). I use Opera Mini mainly for reading forums, online news articles, and the like.
Plus i'm still having the same issue where I flip my TP to landscape and it goofs up Opera Mini. Which doesn't seem to be fixable in the new 5 beta (where as in 4.2 I could select a text box, then hit cancel to come back to normalized screen).
