This is a new rumor although the fingerprint sensor is one that we have heard before, and a rumor which has been fueled by Apple’s purchase of AuthenTec. This isn’t the first time Apple has chosen to use sapphire as they have used it for the camera lens on the back of the iPhone, one of the reasons being that it is pretty durable and hard to scratch, which we guess is pretty important since no one likes photos where the lens’ scratch marks can be seen.
Replacing the physical home button with a capacitive one is a pretty major design change, and looking at the history of iPhones, the “S” iPhones tend to feature upgrades under the hood, such as a faster processor, better camera and so on while keeping the current design of the device. Take this with a grain of salt for now, but we’re sure that many iPhone users wouldn’t mind seeing a capacitive home button, right?
