Does iTunes balance transfers when you change country? I noticed there is an option to change country in iTunes (after I signed in). 


Does the iTunes account balance transfer from the current country to
new country? 
Where is the currency exchange rate (to be applied)
listed? Please provide URL.
I opened my iTunes account in the US in 2009, and then moved back to Norway in 2010. After asking customer support, I learned that I needed to use up (most of) my remaining balance before I could change country, and I lost the remaining balance when doing the switch. (This was no great hardship to me. I had to use gift cards to pay when I was in the US, because my only credit cards were issued in Norway, so the balance was never very high to begin with.)

Of course, that was two and a half years ago, and procedures may have changed since then.
