If anybody really knew, you'd see it plastered all over the forums. As it stands, the closet estimate is middle to late July, and that's not even official. My guess is that they wait until after the 30 days are up for those who bought a black one on launch day! ;-) Otherwise, they'll probably have a good number of people who return the black one and purchase a white one. That said, I'm guessing the white ones might start showing up at the VERY end of July or early August. On the other hand, if these antenna issues have somehow caused a change in the production lines, it could be later...
