Hi, I have a 3GS, and a Canadian iTunes account. I have a question though: I'm moving back to my home country soon. Can I use a credit card from a different country to continue using the canadian version of the iTunes store? If not, I will need to make a new iTunes account with my home country's iTunes store. Will I still be able to use all the apps I already have now? What I mean is, can I sync one phone to an iTunes that has apps from different user accounts?
