I have the iPhone 4. When you push the screen to the far right a tab opens up where you can search the phone apearently. I typed in a few letters and it brought up deleted emails. How is that possible? Is there anyway to clear that? It had a little blue dot next to the subject line when it listed them but not on others so I'm assuming that means it was deketed, but why does it still show up if I go in Yahoo and they are deleted?
