This manual shows Apple’s new iPhone has a different home button, complete with the much talked-about silver ring.
The home button is labeled as a “Touch ID,” which would presumably be Apple’s new fingerprint scanning technology.
The fingerprint scanner is said to be used to unlock the phone. It is the primary new feature for the iPhone 5S.
You can take this as being as truthful as you wish – you know how leaks can be. The good news is that we’re only a few hours from the official event so we’ll all know soon enough if it’s legit.
