Set up mail on iphone 4s, ipad2 and imac with identical settings. Mail is received on all three devices. But on iphone, after a few hours, all emails disappear--totally gone, not in trash, nowhere to be found on iphone. But all messages remain on ipad and imac. Did not have this problem with 3Gs. Have deleted mail accounts and re-entered them several times, but issue still continues. Went to the "Genius" bar and all that happened was that the "Genius" screwed up my mail account settings, which I've since fixed.
Any advice out there?
