I want to install opera mini on my N900.

I'm starting here:
http://www.nokiadistrict.com/opera-mini-for-nokia-n900/

which first takes me off to install java here:
http://www.nokiadistrict.com/install...on-nokia-n900/

instructions:
Icedtea6 is allegedly installed, but it doesn't show in apps list (is it supposed to?)

I've downloaded Microemulator, which apparently was saved in downloads.

I've also (allegedly) installed <someone's> unzip from app manager.
I say someone's as it is not appearing either and I can't remember the name exactly.

Now assuming I have installed what it told me so far, I am falling over now.

I'm not stupid or a technophobe, but I am un-knowledgeable in the x-terminal part.

Is there a do this next do that next version?

For example, I take it I need to install rootsh?
That is skipped over.

the unzip, (which I tried) couldn't find the downloaded file.
Ok makes sense, I'm probably not in the right folder.

Instructions don't cover that.

Is there a muppets guide to it??

cheers
