I know of a few places that were able to unlock the Rogers 8100 BlackBerries but haven't done so in a while as they haven't been able to get the codes however from what I hear they will be able to unlock them in the very near future.

Also unlock isn't available for Cingular customers... the T-Mobile branded 8100 BlackBerries can be easily unlocked for use on T-Mobile if someone wants their device unlocked or to use on a network such as Cingular or Rogers. My Pearl is T-Mobile branded and had it unlocked so I can use it on Rogers.
