A Japanese parts company, Moumantai, says it has obtained a logic board for Apple's next-generation iPhone, commonly expected to be called the iPhone 5S. The board is similar in design to the one for the iPhone 5, but shows some significant differences in the layout of its chips, circuity, and holes. While no chips are actually attached, the space for the main processor hints that Apple's next A-series chip will be larger than the A6.
