I think this has a good fit in this questions & answers thread, especially for people who bought or intend to buy the N9 from another country:

Nokia warrants to you that during the warranty period Nokia or a Nokia authorized service company will in a commercially reasonable time remedy defects in materials, design and workmanship free of charge by repairing or, should Nokia in its discretion deem it necessary, replacing the Product in accordance with this Limited Warranty (unless otherwise required by law). This Limited Warranty is only valid and enforceable in the country where you have purchased the Product provided that Nokia has intended the Product for sale in that country. However, if you have purchased the Product in a member state of the European Union, Iceland, Norway, Switzerland or Turkey and Nokia originally intended the Product for sale in one of these countries, this Limited Warranty is valid and enforceable in all of these above listed countries. Some limitations to the warranty service may apply because of country specific elements in the Products.

So within the EU it should be no problem to claim your warranty in the UK or Germany for example, with reference to that policy, which Nokia states on its own website.
