Did you miss out on Apple's free case program for your iPhone 4? If so, you're out of luck. If you have reception issues with your iPhone 4, you can return it as usual, but at this point, Apple believes that everyone should know about the Antennagate issue, so there are no more free cases.
This also means that bumpers are back on sale. While you could easily get a free one, they disappeared from Apple Store shelves, but as of today, bumpers are reportedly available again. Unfortunately, they're still not for sale online, but presumably that will be fixed soon. Word has it that they're heading back to the US$29 price point, too.
If you're buying an iPhone today or in the future, what are your plans for a case?
