Hi, I am going traveling to Australia for 4 months this year, and I am planning on taking my 3g iPad 2 with me. It is currently unlocked, with wifi only being used, but when I get there I plan to connect with Telstra on their 3g plan for monthly data use. My question is when I come back to Canada, will I be able to insert a Rogers microsim card and sign up with them? or will I now be locked in with Telstra? I am moving this thread to the australian sub forum Thanks!
