You could be looking at the next iPhone. It's still a prototype, yet it is starting to reveal a few interesting specs.
MacRumors was able to grab leaked photos of what looks to be the next iPhone, reportedly dubbed as the iPhone 5S. Perhaps the most interesting image is the one showing the main chip of the iPhone 5S, which does not have an A-series identification printed on it.

A closer look at the image reveals the APL0698 model number. If we'll compare this number to the iPhone 5's A6 chip (APL0598), you'll notice the slight increment in the second number. MacRumors notes that this could be an A7 chip.
Additionally, date codes on the chip also indicate that it was manufactured in October last year. We're referring to the 1239 date code which represents September 3, 2012. Another interesting code is the K1A0062 identifier.
The folks over at Chipworks are saying that previous Apple chips typically had the letter "N" which refers to Samsung, a long-time chip supplier for Apple. The change from N to K, according to Dick James and Jim Morrison of Chipworks, has something to do with Apple's decision to dump Samsung in favor of TSMC.
This is interesting, considering DigiTimes's report yesterday that Apple and TSMC already tied the knot.
