For anyone interested Go here and enter your serial to see if you are eligible. If you are, you've got a window of two years starting from your original purchase date for replacement. Apple takes your phone for 4-6 days. They will give you a 16GB loaner if you require one. If you replaced the button before and paid for it, see the bottom of the page for contact info. If you are on iOS 6 it seems you will be forced to upgrade to iOS 7. Note that this does not seem to be a replacement of the entire phone, just the button.
