There are a lot of games and other apps in the US App Store that I'd very much like to download and that are not available in my country's store. I also like to read users reviews before purchasing an app but there are very little reviews posted, unlike the US store. So can I set the App Store to the US even though I'm not in the US? Will I have problems using the apps, updating them, etc.? Same goes for the iBookstore, very small collection of books. Can I change the country to the US?
