Downloading the application that you can... wait? An application to get a free case from Apple in response to the whole antenna issue? That's kind of funky. I assumed that it would be something you would log into the on-line Apple store or even the brick-and-mortar stores to get sorted.

Apple is always doing things a bit differently, but I assume that this Application may have more going on that simply placing an order. It would not surprise me if in the background it is also scraping logs from the phone to analyze data on the device's antenna performance. Or it could simply be a convenient way to make sure that only iPhone 4 users register for the cases. Hmmmm makes you sort of wonder though.
