iphone temporarily deletes messages
so I just updated to ios7 and my phone has been perfectly fine. the battery died once and when I turned it back on all my messages (both text and imessage) had dissapeared and then a couple minutes later the imessage ones appeared, but not all of them. then when I would go back to create a new message and type their name, our previous texts would show up and it would put their conversation into my messages. so I had to manually add back all my messages.
also it has not notified me at all of me getting any messages, no vibration no little 1 in the corner saying I have anything but when I actually go to messages it would show that I have a unread messages.......
iPhone 4, iOS 7.0.2
