Jobs and Schiller on why it took Apple ten months to produce white iPhone 4

Did you ever wonder why it took Apple ten months to produce the white iPhone 4, which finally goes on sale tomorrow? According to The Wall Street Journal's Mobilized blog, white iPhones need UV protection. Author Ina Fried interviewed both Apple's boss Steve Jobs and marketing honcho Phil Schiller. The latter said:

It was challenging. 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.

And here's from Jobs:

We obviously think about this in a generic way because you have a white iPad.

Jobs also confirmed that an upcoming iOS update will address that location tracking issue that Apple earlier today characterized as a "bug" and confirmed Apple will next week testify in a Congress hearing about location-gathering practices.
