Ghost emails after iOS4

[Ripper2009]

Updgraded my 3G to iOS4 and now keep getting emails from (No Sender) with (No Subject) sent on 01/01/1970
Any one else seen this?

When I try to open one they all vanish

what the hell and its from 1970?

LMAO

Workaround that does it till they fix it:
go back to your mail root and select sent items, then back to root and inbox again. That did it for me.
Feels like it has to do with the treaded inbox, not sure if turning that off helps.
Good luck.
