The 5S/5c was released in China the same day as the US.I don't believe it will affect opening weekend sales since demand is so high in the countries it's being released in and Apple places a limit on devices available. It may affect Dec qtr sales if It's not release in China in the next couple months.
I don't think so. The fact is Apple keeps a lot of iPhones for its own stores for opening weekend. If that's the case, they aren't considered sold until Apple sells them to the end customer.So not stuffing inventory at all.
