would an unlocked Tmobile phone work with canada's BELL NETWORK?

i live in canada , and i reallt want the new blackberry curve 8520, BUT my carrier , Bell mobility, doesn't have this phone. My question is; if i buy the new curve online from tmobile , and unlock it , will i be able to activate it to my bell network??

Yes, you can swap to any GSM networks once you unlock your phone. I did the same to my Blackberry Curve 8520 using the permanent unlock service from Mobileunlocksolutions.com and was able to swap networks easily.
