And yet, Apple does, so it's a hint.Markets have segments. Apple decided to sell their 4S through other channels in the US (they still sell it on their site in Brazil, which I guess by your logic proves that they still manufacture it. That is a country of 200 million), likely to continue this absurd and so easily disproven myth, repeated in here, that they only chase the high end.
But then you would have noticed that (a) it is all rumors, and (b) it is from February - 8 months is a long long time in manufacturing.
It actually isn't hard at all, nor are they rumor sites. I'll give you a hint -- Apple moved all iPhone 4s and 4 production to a manufacturer called Pegatron. And before you implore me to provide the research for you, how about you demonstrate a single credible source that Apple ever stopped manufacturing it?
