I'm from the US and currently have an apple ID associated with the US App Store. However, I'm currently in England for the holidays. I've wanted to buy a couple of books from the iBookstore, but I noticed that all the prices have changed to pounds. I don't think I've ever changed the country store (not sure how I'd even go about doing it). My account has some money on it (in dollars), and I was wondering if I could use it to buy the books. Additionally, after I've come back to the states, would the books continue to work (is there even a way that apple could block me from reading books...)? Thanks a lot! P.S. I've only got my iPhone and iPad with me, and both are showing these symptoms.
