My iphone somehow adopted the name of the computer at my workplace because I registered it on that PC

. Is there anyway to change that once its set? I looked in the general settings on the Iphone but I don't see anywhere to edit it. Would you have to call AT&T to have it changed?
The name in question is the one you would see if you go to "General Settings" and then select "About" - your Iphone name appears at the top of the screen.
"Username's Iphone"
thanks!
