Look for the frequencies that the moblicity version uses. If it matches with Rogers frequencies then it will work great.
From Moblicitys website:
Frequencies: GSM Quad band (850/900/1800/1900) HSDPA Tri Band (AWS)
From Rogers wiki:
on the 850 and 1900 MHz bands (Also known as 2G GSM, or 2.5G in the case of EDGE)
on the 850 and 1900 MHz bands (Also known as 3G GSM)
Dont quote me, but I'm going to assume it will work on Rogers.
