Default [Sch-r760] Will Rooting Delete Carrier

Hey, I'm a complete newb to mobile phones. I have a Gereic CDMA Sch-r760x, I found a root guide on it on this forum, http://forum.xda-developers.com/show...php?p=40087292 but noticed it's really for the us cellular counterpart. My question is Will flashing and rooting somehow delete my Mobile Nation carrier information and make my phone think it's US Cellular?
