On the day Apple debuted the often-delayed white-colored iPhone 4, the company’s marketing department gave a nod to the product’s troubled history.

“Finally.” read the big headline Thursday above a picture of the white phone on the homepage of Apple. com.

The white model was supposed to ship alongside the black one at the iPhone 4’s launch(推出) last June. But design and manufacturing complications delayed the process by 10 months, catching Apple off guard, executives say.

As CNN reported last month, earlier test models of the white iPhone 4 produced unclear photos, especially when the flash(闪光灯) was used. Its whiteness confused the proximity sensor (距离传感器) , which detects when the phone is held next to someone’s head and turns off the touch screen to save battery life.

These problems weren’t present in older iPhones that came in white because they didn’t have flash photography; the proximity sensor was unaffected because the front side of previous models was black.

“We thought we were there a year ago, or less than that, when we launched the iPhone 4, and we weren’t,” Philip Schiller, Apple’s chief marketing executive, said in an interview. “It’s not as simple as making something white. There’s a lot more that goes into both the material science of it —how it holds up over time…but also in how it all works with the sensors. “

Ticonderoga Securities analyst Brian White predicts that the white model could help drive sales of Apple’s phones. He says Apple could sell 1 million to 1. 5 million every three months until the next iPhone model is unveiled, which is expected to be this fall.

Forty-five people were lined up at Apple’s flagship New York store Thursday morning to buy white iPhones, according to a CNN Money report.
