Is the Nokia 1600 quad band? ie, 850, 1900, 900, 1800, as specified in the user guide.
Or dual band, 850, 1900, as suggested by the Nokia Canada's web page?

It's more like different markets/continents than different carriers. I don't expect Mexico to make all the 1600s in the world either. 😉
Manufacturers usually offer different specs in different markets and price ranges, in order to reduce parallel imports and maintain product differentiation.
Anyway, Nokia UK clearly states the 1600 is dual-band, even though all 4 frequencies are mentioned like our User Guide does:

While Nokia USA only mentions 850/1900 (i.e. North American GSM) :

My guess is that it supports whatever dual band is enabled in the firmware. So if you want to use it in another country with a different band frequency, you could backup your phone firmware and install the new firmware with the correct band. Or it could just be a SEEM edit to switch between which band is enabled theoretically you might be able to enable all bands

Just an update. I still have not received any email from Nokia's customer support on the question.
But I did notice the printed label on the box that states "For use on GSM 850/900 networks". It's the label that states the IMEI, so I guess this is more authoritative than the manual.
So I think using this oversea should not be a problem as 900 is a common frequency for other parts of the world.
