Another HD video of the Champagne color iPhone 5S has made its way on the web via TDL. The video among other things, confirms that the color of the iPhone 5S shown is Champagne and not Gold as is widely reported.
The video illustrates the difference in the positioning of screw slots in the back housing of the two phones. Additionally, there is the change in the shape of the flash opening to pill-shaped instead of the circle in the current iPhone 5. This is expected to be a dual-LED flash, which would significantly improve the quality of photos taken in low light conditions.
