Ever wanted to QUAD boot your Nokia N900 ? Of course you did !!!! Here is Maemo Community member Skykooler giving you the run down of what you need to do. Full instructions found in the link at the bottom of the post.
Putting together instructions from various threads, I now have a quad-booting phone. Why, you may ask? Because I can. And because there are more apps for Android, Meego is under more active development, Maemo is more stable, and Kubuntu just plain looks cool. I decided to post how I did it.
