iPhone4 - Delete everything and start up from the beginning
I have an old iPhone4 I want to use for a simple purpose. It is connected to an old Apple-ID that is not operating anymore. How to remove everything and start it up from the beginning again. The problem is that the phone start uo with a activation lock that belongs to the old Apple-ID so I can not go in to the phone and do it from there. I have installed a new version of iTunes but the same problem with the acitivation code is there.
