How do I rename my apple id in iphone?

Hey there!

To rename your Apple ID, just follow these simple steps:

1. Open the "Settings" app on your iPhone.
2. At the very top of the page, just below the Search bar, there will be a button with your current Apple ID photo along with your current name. Select it.
3. Select the button that says "Name, Phone Numbers, Email"
4. The top button will say "Name" along with your current Apple ID name. Select it.

Now you can change your First, Middle, and Last name.

I hope this helps!
