I have won a Nokia Lumia 920, yay! However, it did not include a plan...the phone was won through a Roger's contest. So now, my problem is, how the **** do I unlock it to use with my existing Koodo account? I am on a limited budget, so I can't go through a lot of money to do this, but I don't want to brick the phone before I even get a chance to use it. What can I do?
