While it may seem ridiculously premature to begin speculating about the next-generation iPhone, not even two months have passed since the iPhone 5 was released and we're already hearing chatter about the next-gen model - the "iPhone 5S."
Now, before we go any further, it's important to point out that at no time has the source of this information suggested that the iPhone 5S is coming soon. It isn't. Merely a trial production of the device is going to commence next month, although it isn't yet clear what the hardware looks like.
Apple is expected to begin trial production of a new version of its iPhone 5, or iPhone 5S, in December with initial production volumes likely to top 50,000-100,000 units, according to a Chinese-language Commercial Times report.
