I bought my iPhone 4 in France, but since then moved to the US. I have changed my address, my phone number etc. associated with my Apple ID, but the prices of the apps in the App Store still appear in euros. This is a problem because I would like to purchase apps using my US credit card, without my US bank making me pay foreign currency fees.
So. I've looked on the internet and here but came up short on how to effect a switch.
How do I change the currency on the App Store? Or is there any other way to solve this problem?
