This august, my mother and I are going to Norway for a church trip. We live in iowa and both have cell phones from our carrier, Verizon wireless. What I espcially want to know is can we use our cell phones in Norway? Do we have to buy something specific? Are we going to be using roaming? Help! Also, itouches work everywhere right? I just got mine 3 days ago.. I don't know very much about it yet. Thanks!
