Here is a rather interesting iPhone online support thread on this topic: http://discussions.apple.com/thread....readID=1786497
Please help! I took my husband's i-phone and found a raunchy picture of him attached to an e-mail to a woman in his sent e-mail file (a Yahoo account). When I approached him about this (I think that he is cheating on me) he admitted that he took the picture but says that he never sent it to anyone. He claims that he went to the Genius Bar at the local Apple store and they told him that it is an i-phone glitch: that photos sometimes automatically attach themselves to an e-mail address and appear in the sent folder, even though no e-mail was ever sent. Has anyone ever heard of this happening? The future of my marriage depends on this answer!
Apparently the image was of the man's genitals... More here
