I'm not saying that Apple didn't send out any iPhone review units, but they sent out very few (probably in the single digits). It makes sense, since everyone is worked up into a froth at the moment about the iPhone. Apple doesn't need to beg publications to review this thing, they will be selling a boatload of 'em anyway.
That being said, you would think a magazine like Popular Science would be able to get their hands on an iPhone ahead of time. It would appear not so much. The emails traded with Apple are particularly amusing.
So, while you're online for an iPhone look to your left and your right.. you just might see some tech reporters anxiously hoping to get their iPhones before deadline.
