I have a problem
I have a problem with activation my iPhone 4s. I have bought the iPhone in a shop long ago and update iOS 8 yesterday. After update iPhone has an activation screen and asks previous owner's Apple ID and Password. I don't know Apple ID and Password; I haven't comunication with him. I can not use my iPhone 2 days. I am so disappointed this situation/ Can you help me to disable this function, please?
