Just checked all the options on amazon.com (5S, 5, 5+sapphire, 5X) and they are claiming Feb 21 availability for all of them, which I find a bit hard to believe. Probably an data entry error somewhere from amazon.
Seems to be they fixed that already, now it says:"This item has not yet been released. "
Amazon US still shows no availability date.
HTH
It said February 21, 2017 yesterday, and still today ON MY BROWSER, WITH ME LOGGED IN:
Amazon shows different information to different people depending on whether you're logged in, your browsing/purchase history, Amazon's cookies on your PC, the browser you are using, your browser cache, and who knows what else. For me, and the OP, it did indeed say Feb 21, 2017. For you, it did not.
A statement like "Amazon US still shows no availability date." is too broad. Different people will get different information depending on many factors.
