Just did a 4.2.1 restore to see if it fixes the problems I have. Still have email push problems. It seems to not pushing my mail. Does any launch daemons affect this cuz I have been removing some launch daemons so I don't know if it affect this email push problem or not. I also have delete and recreate the email twice. Still same thing. Just delete the Yahoo mail account again and restart the phone. Then going to recreate it then reboot again and see if it will work. Not sure if that many reboots are necessary lol. Any ideas?
Hmm, this clean restore seems to fix the problems. Will post if it occur again. Thanks for all the great help!
