CBS takes shows mobile

CBS has released an app for Apple mobile devices (using iOS) that will provide direct access to current network programming.  (The network indicates that Android and Windows 8 versions are in the works).
  The free (but ad-supported) app allows users to watch full shows streamed in HD, and includes live social feeds for fans to chat with one another.  The network indicated that most daytime and late-night programming will be available within 24 hours of initial broadcast, but prime-time programs will normally be available only after 8 days.  It also seems that for now, at least, not all programs will be available through the app.
