Nokia 2760 unlocked? | Petro Canada Rates and Plans | Consumer forum

I'm looking at purchasing the 7-11 Nokia 2760. I currently have a "chocolate" POS phone provided by my company. I would like to take the SIM out of this phone and put it in the Nokia 2760. That is, is the 7-11 Nokia 2760 locked or unlocked? I see others have used the SIM out of the pay as you go into other unlocked phones, but has anyone tried it the other way?
