Has anyone else experienced the very bizarre email problems that have appeared since updating to OS4 on the iPhone? I updated my 3GS when OS4 came out and everything was fine till about four days ago when I started getting emails dated 01/01/1970! They have no sender, no subject and can't be deleted. They also do not appear if you were to look at your emails on a computer, they just appear on the iPhone! The only way to get rid of them is to turn the phone off and back on. This usually sorts it out for a few hours but the emails eventually reappear when you refresh the inbox.
I am getting pretty fed up with it. Is anyone else experiencing this problem?
