To change the name of your iPhone, iPad, or iPod touch, follow these steps: On your iOS device, go to:
Settings > General > About
Tap the first line, which shows the name of your device. Rename your device, then tap Done.
Change the name of your iPhone, iPad, or iPod using your computer - Apple Support
(Note, the title of this document is misleading since the first half tells you how to do it on a device itself without a computer.)
