Charging extra may bring about bad PR for Apple. Apple wouldn't do it to their loyal fans. Who lined up on July 8-11 depending on how dedicated (Crazy) you are.
I agree completely. At last years WWDC, they made a very big deal about how the price of the original iPhone was too high and how $199 and $299 seemed like the perfect price for the iPhone. Turning around a year later and slapping their customers in the face, the very same people who bought an iPhone 3G BECAUSE it was 200 dollars with a price tag of 500 dollars is a horrible business plan.
