I ordered mine through nokia usa. I had some initial problems and had to exchange my first one (sad times). I had no problem contacting support ever (called them many times now) and my new device is working as I expected the first to work. the number I used is

(888)-256-2098 ---- Nokia USA. They also list other numbers in the recording when you call them if you need specifics. Worked for me. I am on device number 2.
