How to load the App Store directly from an app?

[LotsOfQuestions123]

I need to figure out how to load the app store from one of my applications by clicking a button. The code is relatively easy to load say a website. But when I use this code:

-(IBAction)goToAppStore;
{
[UIApplication sharedApplication openURL:NSURL URLWithString:@"http://itunes.com/apps/appname"];
}
it does not work, because it says too many redirects occurred.

Is there a way to load the app store (and load into a specific app info view) directly from the app, instead of loading a website to load the app store?

Thanks very much,
