Wirelessly posted (Mozilla/5.0 (iPhone; CPU iPhone OS 5_0 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9A334 Safari/7534.48.3) The weirdest thing keeps happening with my notification center. It works when it wants to, but 90% of the time it just doesn't work. I swipe down from the top and it doesn't appear anymore. I restart my phone and it will work for a few minutes and then it won't work anymore. Frustrated. Anyone else having this issue? Another issue is in iMessage. I get the 'delivered' message and I can see when someone is typing, but I don't get the 'read' message.
