By now you must be more than familiar with how the forthcoming iPhone 5C and iPhone 5S are likely to look, courtesy of numerous leaks. Adding to the already long list, is a video posted by AppAdvice, which shows the back casings of the gold colored iPhone 5S and the blue variant of the iPhone 5C.

The near four-minute long video shows the gold variant of the iPhone 5S alongside the aforementioned blue variant of the iPhone 5C and the two iPhone 5 colors. The iPhone 5S looks strikingly similar to the iPhone 5, with the only visible difference being an elongated flash unit, which could house the dual LED flash module that was leaked earlier. Additionally, the iPhone 5S is also expected to feature an upgraded camera and a fingerprint scanner.

The iPhone 5C plastic back panel, on the other hand, remains consistent with the previous leaks. It is likely to be offered in two variants—codenamed ‘Zenevo’ and the ‘Zagato/Bertone’. The variants are said to look the same but will feature slight differences on the hardware front. Zenovo is reported to feature a dual-core Samsung H5P processor, 1GB of RAM and Bluetooth 4.0, while the Zegato/Bertone, is said to feature an H6P processor and 1GB of RAM, and Bluetooth 4.0. Additionally, the phone is also expected to sport an 8-megapixel rear camera.

Both the devices are expected to be announced on September 10.
