The most expensive mobile device ever - which will retail at $999 for a 64GB model - was unveiled at the company's new Apple Park headquarters in Cupertino, California on Tuesday (12.09.17), but won't be available for pre-order until October 27, a week ahead of release.
Apple CEO claimed the iPhone X, which is pronounced iPhone Ten, will "set the path of technology for the next decade" thanks to its state-of-the art functions including wireless charging, edge-to-edge display and Animojis, which uses facial recognition software to customise existing emojis to the user.
The device also boasts a 5.8 inch OLED "super retina display", a dual camera and a Siri side-bar, as well as Face ID, which has been hailed as "the future of how we unlock our smartphones" thanks to its seven sensors to recognise the user.
Apple Vice President Phil Schiller said: "The chance that a random person in the population could unlock your iPhone X and unlock it with their face is one in a million."
The iPhone 8 and iPhone 8 Plus were also announced yesterday.
They will come in 4.7-inch and 5.5-inch models respectively, costing $699 and $799, and will be available in silver, space grey and gold.
Differences from the current iPhone 7 include glass backs - which have been described as "the most durable glass ever in a smartphone" - 3D touch and wireless charging.
And Schiller hailed the new models as the first "designed for Augmented Reality."
Pre-orders start on Friday (15.09.17), ahead of going on sale on September 22.
