Hello, I spend my time between the UK and France. I want to download an app that seems only to be available in France. Can anybody tell me if I set up an Itunes account in France in addition to my existing UK account I will be able to sync both accounts to my Iphone?

Also, having just foolishly upgraded to Itunes 10 (Nas not supported) can anybody tell me if they too are having problems trying to restore Itunes using a Time Machine backup.
Grateful for all help.
