The hype surrounding Apple’s second-gen iPhone is starting to build up yet again. The latest rumor? Gartner analyst Ken Dulaney believes Apple has just placed an order for 10 million units of a second-generation device. This could mean two things- either Apple is coming out with a 3G iPhone, or it has great confidence in its current model.

In another interesting twist, Dulaney also predicts that the 3G iPhone will ditch the current LCD display in favor of an OLED panel. The introduction of an OLED display will allow the iPhone to be slimmer and more power-efficient.
