Can anyone please help? In trying to upgrade to iOS 7 I lost everything on my iPhone. Two years ago I was advised by my provider to get my phone unlocked "a few doors away" as they could not unlock it. This I did (Now I know to be unwise) but I am not highly technical and thought nothing of following this advice. I appealed to the CEO of Apple. They said only Orange (my first provider) could unlock it. I then appealed to the CEO of Orange who never replied. So I have a useless iPhone and cannot interact now with my iMac or iPad. Can anyone please advise as I am a 74 year old man who up to recently enjoyed using all these items. Many thanks Terry Davis
