White iPhone 4
Your best bet, if you want this and still want to get the iPhone 4xx or 5 or whatever comes out this Summer, is that you just go head and sell your black iPhone 4 for about $500-600 on ebay, and come out of your pocket for the difference between the 599-699 outright price of the white one when it leaks. You'll pay like $100 for a color change but oh well.
