So all you guys asking about "does the 5s have a storable chip info"
The thing is, imagine an abacus. You have three reds and then three blues.
Of course it is a row of chips reading 1's and 0's. But the chip reader
inside the phone sees the three red and three blue and says ok.
It is hard wired, in chips. It is not a readable programme as such
the chip just read a series of chips under the home button, it then
does it's thang and says yep, ok that's the right chips in the right order.
Maybe to expand a little, there is an algorithm that , after the chip on the home button
is "read", it puts the algorithm into play and says yep, 37 that's the one.
The bottom line is, there is no programmable information to be stored
