Any customers that didn't receive the SMS message sent by Apple through AT&T are still eligible for the recall replacements if they do not already possess the updated version that has shipped with newer iPhones. The correct version has a green dot on the face with the protruding prongs, while the faulty version has no dot. The instructions that come with the replacement request that the recipient switch the new adapter for the old one, reseal the box, re-label with the included return label, and drop it off at UPS.
