Three UK accidentally made their white Engadget.
Looks like somebody pulled the trigger on an order page for the mythical white a little early over at Three UK. The phone that had previously been listed on the carrier’s site for a long, long time (sans any ability to actually order it) has now sprouted up a page all its own with the magical option to "buy now." We managed to get all the way through to an order confirmation page, so if it’s a mistake it’s a very thoroughgoing one.
Earlier rumors had pegged the white 4 release to April 26th.
