Hi to everyone! I was looking a lot for this information but found nothing. Hope you can help me. If I bought the sealed Sprint iPhone 5 on ebay without contract, as I understand it will be necessary to activate it on Sprint first and then ask Sprint for unlock. Is it possible to do outside United States for non US citizen? Some people says that it will immediately work with another SIM card without activation on Sprint. But I need to know exactly. Hope for your help.
