I'm not a fan of the iPhone, because of its proprietary software and Digital Restrictions Management (DRM).
Sometimes people e-mail me from iPhones, and so I see that little "Sent from my iPhone" note at the bottom of their messages.
While I would prefer that people change that note (if Apple allows them to do that) to say something like, "The iPhone is Defective by Design (http://defectivebydesign.org).", my second choice would be to just not see the note. Fortunately, in Gnus — my favorite free software e-mail client — it's easy to "wash" messages.
Today to my
.gnus file I added:
(setq gnus-parameters '((".*" (banner . iphone)))) (setq gnus-article-banner-alist '((iphone . "\\(^Sent from my iPhone$\\)")))
Now I don't have to see those notes.
