Next iPhone appears to be named iPhone XS and come in gold


9 to 5 Mac:

We believe that the new 5.8-inch and 6.5-inch iPhones will both be called iPhone XS. We also believe iPhone XS will come in a new gold color option not previously offered on the new design. Apple leaked its own gold version of the iPhone X through the FCC, but it has not been available to purchase
.
Other details are still to be determined, but we can report with certainty that iPhone XS will be the name, the OLED model will come in two sizes including a larger version, and each will be offered in gold for the first time.

9 to 5 Mac has what they report as a marketing photo of the new phones, which resemble the iPhone X, but in gold color.

The new devices are expected to be announced on September 12th at Apple's special event.
