wonder how many of those sales were in the last week?
I got an iPhone in Oklahoma City last Friday. I asked them how they had been selling (this was an AT&T store--the Apple Store is closed for renovations). The guy gave me an essay--they sold out every day for a week (that was just like 40 phones/day), then it trickled of till they'd sell just 3-4 a day for a long time. He said they had been selling like hot cakes since the price drop, 20/day or more.
I could easily see them having sold 250,000 iPhones since the price drop last week. $600 for a phone is going to grab you some early adopters (huge numbers in the first days), but it really was too expensive to become a hugely popular phone. Selling it at that price initially was I think a wise decision. For one thing, the device is worth it--or nearly so. But it certainly probably got a lot of people drooling who wouldn't pay $600, and might even be reluctant to pay $400, but since there was a price drop, well, that makes it OK to spend $400. A wise move indeed, I would say.
What a great phone. Other than the fact that I will probably have to have mine replaced over the checkered-dots issue, it's by far the neatest gadget I've ever owned. I can't wait for 10 million users so there is a real fire under Apple's butt to make the OS really classy with a huge array of apps and a third-party SDK like they've already reverse engineered.
