Hi, My friend has a jailbroken EDGE iPhone with software 1.1.4 in Canada and she would like to upgrade it to 2.1, since she asked me to help her with that I have some questions: -Can I unjailbreak the iPhone and make it indistinguishable from standard iPhones? -If I unjailbreak it will it work in Canada since it has the 2.1 software which accepts Rogers and Fido Sims? -If not how do I upgrade it to 2.1? I would like to tank in advance for any help provided! PS.: Now that the iPhone is available in many countries will activated iPhones be interchangeable? Canadian bought iPhones working with Brazilian Sims?
