Yesterday we mentioned that the white iPhone 4 was all-but-confirmed by the Wall Street Journal. But later in the day, something very strange happened - the Three network went live with an order page and shelf date.The page was pulled soon after, but not before The Next Web spotted it. Interestingly, the network quoted a delivery date of 20 April 2011 (which is tomorrow) and the model was the white 32GB iPhone 4. So theoretically, that's the release date.The network was offering it for £159 up front, on a £35 per month, 24 month contract. For that, you got 2,000 minutes, 5,000 texts, as much data as you like, 5,000 Three-to-Three minutes, voicemail and a free iPhone 4 Bumper. Other deals were listed from £25 - £43, but none listed as available.As we said, the page was pulled, so you can't order right now. But with the page ready to go, it looks like Three (and no doubt other networks) will be shipping the white iPhone imminently in the UK. So if you want one, start hassling your favoured network now to get to the front of the queue. You might have one to show off over the Easter weekend.
