There, Apple's policy updated:
"Items purchased at the Apple Online Store that are received between November 1, 2014 and December 25, 2014, may be returned through January 8, 2015. Please note that all other terms and conditions provided in the Apple Online Store Sales and Refunds Policy are still applicable with respect to such items purchased. All purchases made after December 25, 2014 are subject to the Standard Return Policy.".
Edit: I just called Apple, and they said this policy doesn't really apply to iPhones, but they have a little more flexibility with off-contract phones.
