I originally had a UK based App Store account linked to a UK Credit Card. I since moved to Australia. I bought an IPhone, paid for and downloaded the apps I wanted. When my UK credit card expired, I setup an Australian App Store account and linked it to an Australian Credit Card. Now whenever I try to update the apps I downloaded from my UK based account, I'm prompted to enter my UK account details, and get the message that my UK Credit card has expired. I tried to associate my Australian Credit Card with the UK App Store account, but App Store picks up that the card is a non UK one and blocks it. So how do I now update my apps that were downloaded from my UK App Store account?
