Unfortunately not in Canada as far as I know. Both Telus and Bell have phones capable of both
CDMA and
GSM (the motorola a840) but the
GSM band they use is useless unless you go overseas.
There are some very nice phones coming for Telus within the next 2months so just sit tight for a bit. Look at Bell's new Samsung A920, that's a beauty... telus will be getting something similar to that as well as the V3c Razr phone soon (Razr will probably be first week of Feb unless there are further delays). Also the
CDMA razor is actually considerably better than the old
GSM one Rogers carries now!
