Apple internal iPhone 4 antenna support procedures leaked?

A purported copy of Apple’s internal iPhone 4 antenna troubleshooting procedures has been leaked and posted online. Claiming to received the document from an unnamed Apple source, Boy Genius Report states that the list represents the exact procedures AppleCare representatives must follow when dealing with customers experiencing reception problems with their iPhone 4 units. The reps are told to tell iPhone 4 customers to “avoid covering the black strip in the lower-left corner of the metal band,” and note that “the use of a case or Bumper that is made out of rubber or plastic may improve wireless performance by keeping your hand from directly covering these areas.” The representatives are told not to perform warranty service, only escalate if the issue exists when the phone isn’t being held in a hand, and not to offer free bumper cases to angry customers.
