A friend of mine found an IPhone 5 in LONDON. He told me also that before coming back the phone was reported as lost. However, he came back to LATIN AMERICAN and gave me the phone as a gift. The phone is working well but is block so it does not accept my sim card. However, I want to know certain things: 1. I reset the phone so is like new but the phone is Locked and it cannot be use here unless I unblocked the phone. The fact that was declare as lost it can affect any action to unblock the phone? 2. Im going to travel to USA. It will work there if I unblock it? Please no comments about returning the phone because is not posible to me. If could I will do it but Im in the other part of the world besides it has been months so probably the person doesnt care anymore and my friend is not going back.
