I just wanted to know how I could find out the current user's country using Xcode (iPhone Dev SDK).

If you want to get the users country you can do two things. The easiest is to deciper it from their localization settings.
NSLocale *locale = [NSLocale currentLocale];
NSString *country = [locale displayNameForKey:NSLocaleIdentifier value:[locale localeIdentifier]];
This can be unreliable (e.g. a user who is abroad). If you depend on the information you should use CoreLocation to find the users current location and then use reverse geo-tagging to get the country from the co-ordinates. Take a look at the CoreLocation Framework reference. It should help you.
