welcome - welcome to pinstack!
unless it was a used BB with BES installed, you won't need to remove IT policy...but you will probably need to pay to unlock it.
you can always try to call Rogers and see if they will give you the unlock code. it wouldn't hurt...but don't cross your fingers.
another source that seems to have helped a lot out here is

good luck - let us know how it goes!
