I've searched the forums and maemo.org, and not having a lot of lucking finding a nice howto for upgrading my new 770 to gregale. I want to run MaemoMapper, so I figured that's the first step.

Currently, my 770 is running 3.2006.49-2.

I've seen the flasher utilities at maemo.org, and this page:
http://maemo.org/community/wiki/howt...magewithlinux/

But that only talks about flashing to the version I'm already running. I don't understand how 2.1 (Mistral) and 2.2 (Gregale) relates to 3.2006.49-2.

I've tried finding some tutorial about upgrading to 2.2, but haven't had any luck, except to find posts of people who just finished. If someone could point me to a tutorial, I'd appreciate it.

Thanks.
