I noticed Cook used the phrase "sell through" in the press release. So I would assume none of this 10 million is channel fill?
I wouldn't think that anyone has lots of iPhone 6 on their shelves, except for preordered phones waiting to be picked up. In a month or so you will have some amount of channel fill. ("Channel fill" meaning the normal amount of phones that a store wants to be able to serve all customers, unlike "Channel stuffing" meaning an unreasonable large number sent to the stores to be able to report artificially huge numbers).
How about filling your freaking iPhone 6 Plus orders for Americans instead of launching in more countries.
How about selling phones to everyone, not just self-centred Americans.
