White iPhone 4 appears to be ready to order at Three UK for April 20th delivery

Looks like somebody pulled the trigger on an order page for the mythical white iPhone 4 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. Calling up Three's telephone ordering line and PR personnel brought us no closer to finding out the truth, but this particular order page was discovered via a tweet by a Three affiliate -- whose tweets have since gone private -- suggesting it was dug up from someone in the know. Our suspicion is that Apple's finally about ready to dish this phone up to the people and Three has been caught testing out its order page ahead of the inevitable onslaught of white iPhone orders.
