This is a good guide about how to get Opera Mini working....all that's written in there pertains to the official Opera Mini 4 version. Not sure how much of that has changed in 4.1. I don't want to try 4.1 out yet because I rather wait for the official release since 4 is working fine for me now.
This link includes a link to the esmertec jbed with which Opera Mini 4 runs perfectly stable. The default java crashed quickly with my Touch.
