  • Why don't I get notifications when I get a missed call on iPhone? Whenever someone calls me or facetimes me and I don't see it so it goes to missed call. But I'll go on my phone then and I won't get any notifications on the lock screen that I got a missed call. And there's no notification on the FaceTime app or phone app but in settings it says notifications are on. This happened on my old phone, then I got a new one and it was working for a little bit now I don't get notifications again. What can I do?
  • Why doesn't my iPhone 3GS Push notifications work? My fiancé got me a used 3GS (times are hard) and ever since I've gotten it my notifications will not work. The notification buttons are all on. Even when I turn them off and then back on they still won't work. My fiancé is a computer wiz and told me not to restore my iPhone what so ever. Everything is on and sound is great just the push notifications won't work.
