There are so many reasons why the answer is "no."
1. Because a million people already bought them, and plenty are still waiting
2. Because there would be mass outrage for those above, all of the Black iPhone users would then demand a refund
3. It would be Apple acknowledging it even more. Let's face it, the forum and tech sites know that it is a problem, but if Apple lowered the price as a response to a defect, it would be on the front page of CNN - talk about PR massacre.
