Alright, so I live in Canada and I have a Canadian iTunes account. I wanted to buy some apps,but I didn't have much money,so I looked on eBay. I found an iTunes card for a really good price. I bought the card and tried to redeem it. That's when I found out my card was a USA card. I thought no problem, I'll make a USA iTunes account. I did and I redeemed the card, it worked! I downloaded some USA iTunes apps and synced it to my iPad. I was so excited. I opened an app, and it just closed right away. This happened with all the apps from the USA app store. Now I'm sitting here seeing if anyone knows how I can fix this.
