They won't ship until later this year. I've been eagerly awaiting the white one now since they introduced the iPhone 4 @ WWDC. This is seriously pissing me off. I'm at a point where its either buy a black one or wait it out for the next gen. I've held onto my first gen (yes, the edge version) for long enough. Equally difficult to swallow was Apple not allowing for an iOS4 update on the first gen iphones and now I have to deal with this.

White models of Apple's new iPhone® 4 have continued to be more challenging to manufacture than we originally expected, and as a result they will not be available until later this year. The availability of the more popular iPhone 4 black models is not affected.
