Although Joan Rivers may have passed away on September 4th, she just gave a ringing endorsement to Apple's new iPhone 6 on her Facebook page.

TMZ reports that the late comedienne's account posted a promotional tweet for the phone this morning, before it was deleted by a member of Rivers' team.

What Joan would have made of the new iOS8 update remains a mystery, but we're certain she would have had a real zinger about U2's album.
