I think this is why Apple lowered the price. They sold a lot the first week, fewer the next week and so on. the trend was moving the wrong way.

No one lowers a price on a product that is selling faster than they can be made. You lower it due to slowing sales.
What about the iPod Mini? While, no, Apple didn't lower the price on the best-selling iPod at the time, they stopped making it. No one else would do that. Any other company would've milked the Mini for as long as they could. Apple doesn't do the usual.
I think your expectations are way too high for any company actually by expecting them to "sell faster than they can be made". You might point to PS3, XBOX360 or Wii, but if there are any shortages there, I belive it was due to intentionally creating a demand for them by only producing a small amount. Video game players tend to get worked up any way. You tell them there's only a small amount, you're due to sell every one that you make, but then you're limiting your sales too.
But many companies choose to lower their prices when they've reached a certain place in the market so they can broaden their lead and base even faster. If you've been catching some of the tech buzz lately, you would've read that the iPhone outsold all other smartphones in July
Reuters. The iPhone is very popular, but could it sell even faster? Yes. By lowering the price by $200. Steve Jobs made the decision to lower to make the product even more affordable so that Apple could sell even more of them this Holiday Shopping Season. Why don't people just take him at his word? Some people hate those who are doing well. On the street, they're called "Player Haters".
Did Apple lower the price of the $399 iPod by 33% after their first 72 days back in 2002? By your proposed pricing theory, Apple would've done just that. No, they stood by their price as if to say, "This price is justified and if you want it, you need to be prepared to pay for it". I'm sure sales tapered off shortly after Christmas. But Apple stood by its price of $399. The iPhone is now a reality because people began to slowly but surely see the value in the iPod. With each milestone reached, Apple continued to make the iPod more affordable while creating more value into each generation of iPod that it shipped.
Why not buy now? You might wonder "if the iPhone is 'so great', why isn't Apple selling more?" Fair enough question... Just as the people most excited about the iPod (and willing to spend the "high" price to get it) came and bought in the first week of sales, those most interested in the iPhone did the same. And then sales tapered off. That is to be expected. Why? (A) Interest is not as high to immediately buy; (B) More consideration to be given due to high cost; (C) Wait to see public reaction; (D) Wait to save $499-599 to purchase; (E) In the middle of another phone contract and doesn't want to pay early termination fee.
There's very few people who are knowledgeable about the iPhone that wouldn't want one if they were given one. As I mentioned in paragraph immediately above, there are a number of reasons why people haven't bought, some of which are out of Apple's control. At this point, Apple is doing two things to make the next wave of buyers take their credit card out of their wallets. They added value to the iPhone by new features (including the soon-to-be available Wi-Fi ITunes Music Store) and lowering the price by $200. The next wave hits this Christmas.
