A new report by Letemsvetemapplem (via Cult of Mac) shows purported images of the iPhone 5s front panel and the Home button with a Apple Logo
According to the post (via Google translate):
We have now managed to get a picture of the front glass iPhone 5s and home button pressed. It is so far the most interesting one in terms of leakage iPhone 5S.
Button is the first time in the history of iOS devices Apple logo offers, under which it is most likely hiding the fingerprint sensor. Let’s not forget that some time ago there were just concepts that show the Apple logo. Photography comes from a very well informed source, and we are convinced of their authenticity.
