Over on the Stuff.tv forum eagle-eyed robbye91 has spotted something unusual about the latest iPhone TV ads plugging the forthcoming US launch.In a brief flash on the iPhone 'How To' advert (pictured), the settings icon, barely visible in the top right of the picture, seems to have moved on one place to occupy a twelfth slot on the iPhone's normally 11-icon menu (see inset).The offending shot has now been removed from the official ad but still lives on in the world of YouTube. Now the speculation's begun as to what caused the shift. Could it be a hitherto unannounced application has taken up residence further up the screen, or were the ad men just messing with the Apple faithful?Our hope? Well, we'll give you a clue – rearrange the letters P, G and S. Answers on a postcard please.Essentials Apple iPhone Price: £TBA ($500, $600 in US) On sale: TBA (29th June in US) Contact: Apple Related stories: Touch the new HTC iPhone countdown begins Hands on with the iPhone
