Noob here, so be gentle. After reading about rooting my moment, it seems most changes are made to files on the SD card. I have the original sd card that came with the phone and I use a larger capacity card in the phone. Question is, if I had to take the phone to Sprint after rooting, could I just put the original card in the phone and recover to factory? Or is it more complicated than that? Basically, Stock phone on the original sd card and my rooted phone on the other card. Edit: Found the major error in my thinking.
