ther way or an app will show owners name and alt iPhone

Both my old cell phone and especially my BlackBerry have a home screen display (even when locked) that has my name and a basic if found please call xxx-xxx-xxxx message. Is there a way to do this on the iPhone? I get the time and date and the wallpaper photo, but I would love to be able to have something that pops up first thing about if found, please return to...
Just curious.
Thanks
