If you want support from Nokia then you must be prepared to take or send it to the country you bought it in, if you dont then you will not get support simple as that.
In Europe we have the European court of justice and i do not know if a case like this has been presented or not but international support is questionable in any event regarding Nokia, i have always read that devices are only supported in the country of purchase.

I personally would not buy the N9 outside of the country you live in unless your a frequent traveller to the country you purchase it from.

The Nokia "Limited Warranty" states clearly it is only valid for the country of purchase and is applicable worldwide.
