iPhone users will be able to enjoy this season’s NFL football games via DirecTV’s “Supercast Mobile” app. Despite the app is free — still coming soon to the App Store– and the stream can be accessed over 3G and wi-fi, but the service is not cheap and subjects to local blackout restrictions, too.

First, you’ll need to be a DirecTV satellite TV subscriber. Then you’ll need the $280 NFL Sunday Ticket subscription. And on top of that, you’ll need a $100 Sunday Ticket “SuperFan” subscription. But if you’re already leaning that way, then the iPhone app will be a great addition to your Sunday rituals…

Customers will only be able to watch the games available on NFL Sunday Ticket channels in the local ZIP code of their billing address–blackout rules apply. Due to NFL broadcast restrictions, some games will be unavailable on SUPERCAST based on your ZIP code.
