I just got a Nexus S unlocked from Mobilicity in Canada for $350 bucks Cdn. Mobilicity has a prepaid no contract service for $40 a month which includes unlimited web access and calling to any number in US and Canada as long as you are calling in their zones. Their zones only include major metropolitan areas of Vancouver, Edmonton, Calgary, Toronto and Ottawa. Calling outside their zones is 10 cents per minute. Very impressed with the phone since I am a google and gmail user. All my google apps automatically are connected to my phone. Very impressed with the Nexus S, Mobilicity and Google.
