The white iPhone 4, in 94 characters

How one Twitter post launched a flood of free publicity for Apple

He's no Steve Jobs -- that's for sure -- but Apple (aapl) senior vice president Phil Schiller may have set a personal record for how much marketing buzz he can generate per ASCII character.

Responding to a request on Twitter, he let slip that the long-delayed white iPhone 4 will be available this spring.

By Monday morning his 94-character (including spaces) reply had generated more than four dozen news stories and blog posts and was one of the lead items on Techmeme, a closely watched tech news aggregator.

That's nothing compared with what Schiller's boss can do with a single e-mail, but pretty good bang for the buck nonetheless.
