Going with Apple's history it was OS X (standing for OS 10) in older versions of Apple's operating system.

So with the new iPhone should I be calling iPhone "X" or iPhone 10?

What did they use in the announcements?

The device is called iPhone X, pronounced iPhone 10.

The pronunciation follows on from (Mac) OS X being pronounced 10. In the special event, the announcement called the device out loud as ‘iPhone 10’. This is continued in the Apple video ‘Introducing iPhone X’.

This screenshot is showing the YouTube generated subtitles, as the manually written subtitles print ‘iPhone X’, which is what it's called but not how it's pronounced.


its called the iphone 10 but they use x as roman numerals

  • @StrawHara it is not logical that Apple went 7,8,X. Logically there should be a 9 which I think presents why people are confused.
