Can a blackberry curve 8520 with bell be unlocked for telus? PLEASE HELP!!?

I was thinking about buying a used blackberry curve 8520 from a friend. The phone is originally with bell, but I was wondering if I could unlock the phone so that I could use it with Telus. (I'm with Telus)
(I also live in Canada)

ANY ANSWERS ARE MUCH APPRECIATED!

Yes, you can. I suggest you can approach Mobileunlocksolutions.com and get the permanent unlock code for your Blackberry 8520. For free unlock instructions visit Mobileunlockguide.com and once unlocked you can swap with other GSM networks.
