you havent lost warrany mate..in any case. you should contact amazon directly and tell them that you are going to send it to them- i have done this a lot of times with other tech parts and webstores..they accept it usually..if not, then visit a nokia centre at your country:

dont tell them that you bought it from amazon-yet. ask them if it under warranty(because in some companies the support is valid international but they are lazy to check, so they simply say no without checking). if they tell you that it it(they check though computer-at least in my country that i have been through service issues at nokia stores.

in any case if its a faulty product you SHOULD BE covered by warranty.
