Recently, the iPhone X was certified by the Federal Communications Commission (FCC), which means that Apple can now remove from its Web site in the absence of government regulators authorized to sell or lease equipment without disclaimers, while iPhone X has been in The United States is on sale.
The FCC is testing all mobile phones in the United States, supervising and ensuring that these handsets do not produce harmful interference or make users at risk of radio frequency (RF) levels.
Many radio applications, communications products and digital products to enter the US market, require FCC approval, which includes all the iPhone.
In addition, iPhone X's pre-order will begin on October 27, the official sale time for November 3. But because the yield of TrueDepth camera is very low, iPhone X supply will be very small, some analysts believe that the iPhone X out of stock will continue until 2018 years.
