When you set up your iPad, iPhone, iTouch, or iPod for the first
time, you assign it a name. In the future, if you give the device to someone
else or you just do not like the name anymore, you may want to change that name
to something else. To change the name of your device, please follow these steps:
Connect your iPad or iPhone to your computer. Once connected,
start iTunes and look for your device name under the Devices
category as shown in the image below.
Finding the device name in iTunes
With your mouse, click on the device name and the name will change
so that you can edit it as shown in the image below.
Changing the device name in iTunes
When the name is in edit mode, as shown above, type in the new
device name that you want it to have and press Enter on your
keyboard. Your iPad, iPhone, iTouch, or iPod has now been renamed to the name
you typed in.
If you have any questions or need help with this procedure, please
ask in our iPad
and iPhone forum.
