Hello to everybody. I present my greetings to you. I have an iPhone 5 bought from a friend for a very low cost. But it has three problems. First, the screen shows the message "iPhone disabled". Second, it is from USA and locked on AT&T network carrier. When I made a check for the IMEI, I learned also that it has an ID on it. Please, do me the greatest favor in helping to understand what it is possible to do to find a global solution.
