Originally they wanted to sponsor flights and accomodation to the next MeeGo Conference. I've good reasons to believe that there won't be another MeeGo Conference that soon. I had two options: keep the prizes and possibly disappoint the first prize winners by telling them next year that they have won something that doesn't exist, or try to get other prizes. I went for the second option. Personally I don't think that these requirements make sense, but I can't do anything against it. It's hard enough to talk about MeeGo in a WindowsPhone target country. So you have two options: register at Ovi store and try to compile your app for MeeGo Harmattan if you want to be a possible winner of a Nokia N9. Or do not register and be a possible winner of any of the other prizes.
