Apple Thoughts: iPhone May Not be Deleting Your Email

"Macworld has stumbled on an interesting bug dealing with how your iPhone deletes (or more accurately, doesn't delete) email."

According to Macworld, if you use your iPhone for email, those messages you have deleted may not be gone. If you search for a few characters or small amount of text in mail, they say you will likely pull up a message that you thought had been previously deleted. If you tap on it, you can open it up in mail like any of your other email. If you then go back to inbox you won't find the message. And the messages supposedly aren't in the trash or the IMAP server either. The conjecture is that they aren't completely deleted from your iPhone. Something to be cautious of if you really want to make sure some of your email is gone.
