When I first set up my iTunes account, I didn't have a credit card, so I set it up as a US account, as this was the only way I could create one without a card (and thus use my iPod Touch).
The downside of this is that now that I am trying to add a credit card to my iTunes account, I can't, because it insists on a state and zip code for part of the address, which my Irish credit card obviously doesn't have.
So how can I switch the country of my iTunes account?

To change stores you can do so on the iTunes Store:
Click "Change Country or Region".
Choose your Country or Region:
Another alternative is to use Apple's Manage your Apple ID site and change your address - next time you use iTunes it will ask you to change your region and verify your address details.
