Have you ever had a magician stand right before your eyes and tell you that he has nothing up his sleeve Have you ever seen a card sharp on a busy street turn up the card you thought of when you know it can't be possible

And have you ever seen a white iPhone that is exactly the same thickness as a black iPhone

I ask because I read a curious report in 9 To 5 Mac. It relays details of a Twitter exchange between a reader, Ernesto Barron and Apple SVP of Product Marketing Phil Schiller-- who has a very sweet profile picture.

Schiller doesn't tweet very often. Indeed, he has offered not one peep since April 14. Yet he is said to have replied, by direct message, to a public tweet by Barron.

In it, Barron wondered why the white iPhone was thicker than the black one. He helpfully enclosed a little picture that seemed to offer sound visual evidence.

Schiller's reported reply was curious: "It's not thicker. Don't believe all the junk that you read."

Um, what do you think

Certainly this is sound advice. I only believe certain elements of the junk I read--principally, carefully selected sections of the National Enquirer, TMZ, and The Wall Street Journal.

However, there appears to be some considerable evidence that the white iPhone is, indeed, thicker than the traditional black version.

I am not sure how much this really matters. The reported difference was only 0.2mm, which, I imagine, is less than the diameter of much of the world's pocket fluff. Still, I know there will be some who will continue to be disturbed by this phenomenon.

Might I therefore ask any highly committed Apple-user, collector or mere eccentric who happens to have both models, to contact us and express their most scientific appraisal of the two versions' relative thickness

Is this truly a mere touch of David Copperfield Or are our eyes being surreptitiously covered in wool in some distortion field of perception Did Apple really have to put in a little more of the white stuff so that the camera worked properly--or, for some other technically beautiful reason
