The photos were spotted on a Photobucket account (via Apple.pro) and show an iPhone 5 which has been taken directly from the assembly line.
The pics present the assembled front panel of the device with an attached home screen button.
The shielding frame for the display and the front-facing camera are also included in the photos.
Japanese blog MacOtakara noticed a square component covered with EMI shielding whose dimensions fit with those of NFC packages containing the 5 x 5 mm chips offered by NXP.
The device also appears to feature a unibody design with a two-toned rear shell.
The iPhone 5 is expected to be introduced at a September 12 Apple event.
