title: My iPhone app needs a persistent network connection...how to specify UIRequiredDeviceCapabilities?
body: <p>I'm trying to set the UIRequiredDeviceCapabilities properties in my Info.plist file. My app requires a persistent network connection. If I look at the definition for the "wifi" key, it says:</p>
  
  <blockquote>
    <p>Include this key if your application
    requires access to the networking
    features of the device.</p>
  </blockquote>
  
  <p>So: does the "wifi" key indicate that I need WiFi, as the key name would suggest? Or does it mean that I simply need network access, as the key definition would suggest?</p>
