The iPhone 5S design may include a new home button that resembles the old iPhone button on the outside, but has a slightly different look on the inside.
The significance of this purported home button part is that it backs up the theory that Apple is redesigning its smartphone internally.
The alleged iPhone 5S home button, leaked to Czech Republic Apple blog Letem Svetem, has a longer, thinner internal connector.
Apple may change up the inside of its phone to make room for a fingerprint sensor that is rumored to be a part of a future iPhone.
Fingerprint sensor could be elsewhere
Speculation that the iPhone 5 fingerprint sensor would be integrated directly into the home button seems to be nixed by this unconfirmed part from the Czech Republic.
However, the fact that its internal connector is smaller may mean Apple is making room for the sensor above the home button.
The company illustrated such a concept when it patented a fingerprint sensor that has a biometric function to unlock an iPhone.
All of this would go along with Apple's 2012 purchase of security firm AuthenTec for $356 million (about UK£229, AUD$375).
Other Apple iPhone 5S rumors
There has been a flurry of alleged iPhone 5S leaks recently, ranging from Apple finally bringing color to its next iPhone to attaching a 12-megapixel camera on the back.
There is also an unconfirmed report that the company's well-marketed Retina display will be even clearer with double the pixel count to 1.5 million pixels.
But none of these rumors explain the reason for a redesigned iPhone 5S home button better than the fingerprint scanner integration.
With of the iPhone 5S and supposedly even a cheaper iPhone mini going into production this month, there will be even more leaks leading up to the Apple's expected September launch.
