title: Can I restrict my iPhone app from being used by iPhone3G's?
body: <p>My iphone app doesn't run well on the iPhone 3G. Can I make it so users with these models can't download the app? If so, what does a 3G user see when they search for my app in the app store? </p>
  
  <p>Does it appear in the store at all for them? If it does, when are they notified that they can't download the app? </p>
