At least four Apple suppliers have cut their revenue forecasts this week, fueling speculation that Apple is scaling back manufacturing of the iPhone.

Apple said earlier this month it would stop reporting individual unit sales and revenue figures for the iPhone, leading some to speculate that the company has something to hide. Reports that its major suppliers are seeing reduced orders for electrical components could shed some light on expected sales.
