So I rooted a week or so ago. Didn't flash any new ROMs or anything, just deleted some bloatware and set up wireless tethering. Right away I noticed the data connection going up and down a lot. Then a few days ago I started periodically getting a black popup with this: ! Data Call Failure Error Code 67 .Registration failure. Your PCS Vision username and/or password may be incorrect. Please try again. When I get it, I just hit "dismiss" and so far, everything goes back to working normally at that point. Still, it's a little disconcerting. Anyone else gotten this popup or had their data connection messed with by rooting?
