For those who still have their iPhone 4, your free case is here: http://www.apple.com/iphone/case-program/

Clever that they made an app for this to validate eligibility. Also allows picking from quite a few different cases outside the Apple Bumper.

Mine is in the FedEx system somewhere, on it's way back to Apple. The local store didn't want to accept it back since the iPhone was an online order. Ended up having to go to AT&T to get a new SIM for my older 3GS to reactivate it. Once I activated the 4, the old SIM was completely deactivated.

I do miss the niceties of the iPhone 4 already. but I also enjoy being able to use the phone part again without a case or other thing on the phone to fix a design flaw. Would be nice if Apple could fix this properly by September, but if not, I'll be waiting for next years model.
