Default How to restore Rezound "modem" settings

I have noticed that sometimes when flashing new roms/ruus the "modem" settings, for the lack of better word, would get restored to factory conditions as well. What I mean by modem settings is things like the phone number (NAM), PRL, data/3G, kind of stuff. So I have to reactivate the phone all over again. II have been trying to figure out what causes this because sometimes its good to know how to restore those settings when they get screwed up. Does anyone have a clue how to do this?

Regars,

UPDATE: nevermind, I just discovered it myself. Flashing a FIRMWARE did the trick - restores modem to default values.
