When you first set up your new iPhone or iPad, iOS assigned a generic name to the handset, using your first name – in my case it was “Chris’s iPhone.”
The name is used to identify the device when you set up a Personal Hotspot, plug it into a computer for synching, or for AirDrop. But, you don’t have to stick with the default name, you can change it.
That’s it, your iPhone or iPad has now been christened with a new name. Be sure to alert the media.
