The PR people from Amazon got in touch after I published my review of the new Amazon Fire Phone (Amazon Fire Phone: Nice but nothing to get fired up about). They had a couple of points they asked me to clarify:
I was, I admit, rather annoyed to think they had sent me the wrong product but, as it turned out, they sent me a second Fire Phone which turned out to be identical to the first one with "Magic Window" instead of "Firefly." Then I realized what the problem might be: Perhaps the phone needed an over-the-air update. Yep, there it was in the "Settings" app in the "Device" section: "Install system updates".
