I am rooted, have not installed the latest update (dunno if there is a rooted version available). My phone showed me that I needed to update but made sure not to do it because I didn't want to undo my root. Yesterday, my phone started roaming all of a sudden. I can't get it to pick up a regular signal. The signal at my apartment has always been really strong (sometimes 4g), so it doesn't seem like there's a reason for it to be roaming (and it's screwing up some of my uses of wireless tether). Suggestions?
