Mail updated date frozen, slow download response
For some reason every time I launch my Mail app on my 4S iPhone, it always says the same Updated date of 1/15/13 at 4:14 pm. It never updates the date as new mail messages are downloaded.
In addition, the download tone doesn't actually sound until a minute or more after the messages are downloaded, sometimes even after I leave the app and go to another one.
Any ideas? I have rebooted the phone, closed the apps, turned off the phone, and none of these fix the issue. I'm almost positive this started after I upgraded to iOS 6.1, but now I'm at 6.1.2 and still not fixed.
Thanks in advance.
