Why it is called iPhone Ten? Not iPhone X !

When people see it first writing as "iPhone X" many people call iPhone X (Letter X), but it is roman number called Ten.

Why it is called iPhone X (10) because it is anniversary of iPhone for 10 year since the first iPhone was release by Steve Jobs ten years ago...
