How are you liking it otherwise? There have been several improvements since you last poked your head in. All you've commented on is the lack of Opera, which I think most consider a plus anyway.
Also, one more thing about Opera. You could try replacing the references to the Opera*****.exe in the posted app.reg to whatever the .exe of Opera mini is named. That might work as far as making Mini the default.
It seems odd to me that you would comment on the lack of Opera as a negative thing, yet it's not the browser you use anyway. You remember that Opera10 couldn't be removed in previous versions of the ROM right? So, you were stuck with 2 Operas. I fail to see how that's a good thing.
HERE is a post about setting Opera Mini as the default. I haven't tried it and the guy that started the thread doesn't ever confirm yes or no, but you could give it a shot. Apparently mortscript needs to be involved with Mini for some reason?? I don't know, but every site I went to about it mentions needing mortscript. Maybe therein lies the difficutly?
