title: iOS Smart App Banners - showing on iPad, not on iPhone
body: <p>As I'm not using the affilate stuff, I implemented the Smart App Banner on my website like this:</p>
  
  <pre><code>&lt;meta name="apple-itunes-app" content="app-id=..."&gt;
  </code></pre>
  
  <p>On my iPad Mini (iOS 7.0.2) it's showing up without any problem, on my iPhone 5 (same version) it's not showing up.</p>
  
  <p>Both got the app installed already (the banner should show "Open").</p>
  
  <p>Do you know what could be wrong?
  Thank you!</p>
