title: How Can I Launch The Appstore App Directly from my Application
body: <p>I've used several apps now that launch the itunes store directly from the app. I'm even using some on my 2.1 iPod 2G.</p>
  
  <p>I know there's a bug in 2.1 that prevents appstore links from working in safari, but somehow people are launching the appstore directly, not even through safari.</p>
  
  <p>How do you do this? Is it an undocumented openURL feature?</p>
