[nfbwatlk] "sent from my iPhone"

[Nightingale, Noel]

Mike and others to whom this question or comment applies:

Why is it that when you send an e-mail, it says " sent from my iPhone" at the end of your messages?  Why does anyone care how you sent the message?  Or, is the message included as a caution to recipients that they should not hold the message up to the high standard they might if you had sent it through some other means?

As a non IPhone user, I find this as curious a phenomenon as those who sign their e-mails with their dog guides names.
