Your two choices:
I setup my iPad1 when I was in the USA and down loaded apps from the US store with my US iTunes account. I have now moved to the UK and have opened up a UK iTunes account. The App Store icon on my iPad shows that I have updates for the apps I purchased in the USA. When I try to download them I am asked to access my US iTunes account. When I enter my password I get the message Cannot connect to the iTunes store. Two questions - 1 How can I download the updates? 2 How do I access the UK app store? Selecting the app store icon always takes me to the US account.
