Bringing back the iPhone headphone jack, in China
The best hypothesis, IMHO from those I've read, to why Apple ditched the jack, was to get a share of the market for headphones - either through their own headphones (Apple-branded and Beats), or through MFI.In any case, now without the jack, they now get a share of any accessory you connect. The adapter, and any 3rd party adapters and headphones, need to be certified as MFI, which includes buying and incorporating the Apple MFI chip (forgot the name) into the design.Which is entirely in their right of course, but it is a consumer hostile move.
