using buildos

[sugarkoalo2]

I have an old 6800 that im just messing around with and about to send back so i have been experimenting with the buildos program and checking out different roms.. I noticed that when i did update the rom it changed the carrier on the phone to cellsouth? i have no clue if thats even a company or not but i watn to upgrade my activated 6800 to win mobile 6.1. I was wwondering if this is going to effect my phone and cause it to not work? In the build os program i always click us cellular as the carrier but like i said earlier it shows on the phone as cellsouth? anyone have any clue as to why it does that and will it effect my phone that i want tto eventually upgrade?
