From observations in the shopping mall and on the street generally, it seems as if it's not enough just to keep your i-Phone in a convenient pocket, you also have to carry it -- illuminated -- in one hand at all times, like . . . well, like no sartorial or cultural trend that I can think of. Victorian gentlemen with their gloves or canes, perhaps?
