Ditto. I uninstalled EVERYTHING Metro including the web, easy wifi, and mail. I kept the appstore just in case to re-install them should I need to, and kept the navigator cuz I still use that, and no problems here. That's not to say for certain that you won't have probs, so I'm not instructing people to do the same, but hell I even un-installed the calculator (sux, no percentage calcs), and the sound recorder. But this is just me.
There is a stock rom available for this phone should anyone need to restore back to stock like I had to do (I apologize if this has already been mentioned here). My dumb@$$ deleted google talk and needless to say, that's not good.
Found the stock rom and started fresh again rooting and deleting everything metro. No more probs.
