The photos were published by Chinese site C Technology.
An evidence of the fact that it is the packaging for the iPhone 5S in the images is that fact that the iPhone on the box is running iOS 7.
On the front cover of the box we see what appears to be the new iPhone 5Sbut with a different Home button, in line with rumors claiming that the button will house a fingerprint reader.
In addition, another possible proof in this sense could be the presence of a silver ring around the Home button. Similar silver rings are present in the invitations sent out by Apple for the September 10 keynote.
The authenticity of the picture isn’t confirmed but it could be the first sighting of the next iPhone’s package.
