My 822 had a constant sync issue (Live account and facebook would never sync) when I got it, It went away mysteriously and hasnt come back. Now my wife's phone was acting strange on her pinned contacts, kicking her back to home screen, emails not sending, texts not going out, all while kicking her back to the start screen. I factory reset her phone (for the second time in a month) and it did not fix it... weird. I then turned off Facebook chat and every thing seems to be working again. What in the world is going on with this issue?
