Depends on your definition of "boilerplate". I consider quoted mailing lists' footers and those stupid corporate legal notices to be boilerplate, and they're generally far more annoying than "sent from my iPhone" because they often separate the text from attachments and the like by more than a few lines.

Worse, quoted footers are often actively harmful, because they contain "unsubscribe" links for somebody else (but all the user can see is "click here to unsubscribe").
