I am ip4 owner, subsidized purchase June 2010, tried and failed for unlock since I am still under contract. So another month now an I should be good. Questions 1. I am in Canada alot for work now and assume I can purchase some sort of prepaid sim once I am in Canada? Where can I buy one? I see none in the airport. 2. Let's assume I do find a sim to buy, my phone number changes to the new sim #? 3. Can I forward my cell # to my new # (assuming I get a new #)? Thanks!!!
