Emails dated 12/31/69
I have had my 4S for about a year now. About once a month ( but 3 times just this week) I get a email dated 12/31/69. This email has no sender, no subject, and no content. I can not open it, nor can I delete it. It appears on my phone, but not my IPad or laptop. It is through Yahoo mail. It deletes itself usually within 15 minutes, but will sometimes, take up to a hour. Any one else experience this?
iPhone 4S, iOS 6.1.4
