These are renderings, but Boy Genius promises we'll see a white pearl before Valentines Day. Apparently on T-Mobile. Reversing the natural order of things, the white pearl will be at first more rare than the black.
Especially since Cingular announced their Black Pearl today.
This means it's on its way to RAZR/Treo status: So beautiful and affordable, that they flood lands until no one wants them.
Call me traditional, but I find the idea of a white "Blackberry" as weird as a black iPod.
