I'm guessing the BB employee is a moron, just like some of the BB employees that posted on this board going "CONFIRMED: BESTBUY WILL CARRY WHITE IPHONE"..."I SAW THEM WITH MY OWN EYES".
Guess what? Those morons saw a white BOX, which actually holds the black iphone 4. (Black top, white sides). They were probably looking at the new 3GS box as the black one, and assumed the white box was the white iphone, when in fact its the iphone 4.
If Apple doesn't have them, BestBuy won't.
And yes, if I magically got an iPhone 4 in white right now, that **** would be on ebay for $3k+. I'd book a trip to Hawaii, and then put $ aside for another white iphone in 4 weeks.
