I have an iPad3 and so far it has worked OK for me. In our family I'm the one who tries new hardware, software etc. and then I can help my husband.
So today I bought him his own new shiny iPad3.
I started setting it up for him. He is not in general an Apple fan, so I was surprised when we got to setting up an Apple ID to find that there was already one for his email address. We were able to get in by changing the password. It then emerged that he must have set up an ID donkey's years ago when he was in France and he had registered a French address.
I have been able to change this to a UK address and to register a UK credit card with that billing address. The current location of his iPad is the UK and everything is set up in English ... except the app store.
When you hit the app store button, everything is in French (not a big problem in itself). It refuses to accept his English card because it isn't valid in the French app store. But we want the English app store. I tried going in via Safari, but still came up against a brick wall. It accepts the UK coordinates for the ID but still insists on behaving as though he's in France and taking us straight to the French app store.
When you hit the app store button on the iPad, you still get the app store in France.
It feels like a closed maze! How to get out of this endless loop? He wants to use his normal email address for his ID.
