I cannot get notifications to work properly!
SMS and iMessage work about 15% of the time.
Email about every 10th email.
Facebook push notifications show up on screen but make no sound.
I also do not think this is speaker or sound related as the phone won't vibrate on silent mode either.
This started immediately after the update so I did a full wipe with iTunes and re-installed fresh and set it up as a new phone...did not restore from a previous config.
This cannot be such an isolated issue, can it?!?!?! I mean iOS 6 has basically broke my notification system.
