I had Sept 30th stuck in my mind. As I had already purchased a case, it wasn't top of my list to immediately take advantage of the program. Today, I install and run the iPhone Case Application. It tells me that my iPhone does not qualify for the iPhone 4 Case Program. Really? Turns out my expiration was really Aug 22. If I had really read the email offer and posts on this site, I would have known this. I call Apple at the 800 number listed on the app. The very nice CSR immediately offers to make an exception. She gathers personal info and Serial & IMEI numbers. She gives me a ref # and asks that I send proof of purchase (ATT confirmation email) to email@example.com. If your like me and missed your window, you may still be able to get your free bumper/case with a phone call (after an 8:00 minute wait).
