Stealth iPhones: Stockpiled at Quanta's Fremont warehouse?

Forbes Brian Caulfield, who's been tracking the mystery phones' progress from China to the U.S., has posted some pictures of piles of unmarked boxes sitting alongside boxes of iMacs in the parking lot of a Quanta distribution facility in Fremont, CA., located between Apple's Cupertino HQ and the Oakland port.

Could they be iPhone 3G boxes? Tough to say, but they've done some actual gumshoeing and posted a bunch of photos of the mysterious boxes.
