GSM850 is a frequency that unfortunately Fido doesn't have any spectrum in
only Rogers does. You can however use 850 in the U.S., some parts of South
America & the Caribbean as they have both 850/1900 networks.

As far as I know there will be no new Nokia's coming out soon with Fido. I
am also a Nokia fan but buy my phones elsewhere. The last Nokia I bought
from Fido was in january & it was the Nokia 7210 (great phone by the way).
