Can someone clarify what the signal display update was done in firmware 2.1?
Here is a screenshot:

The last line of the screen shot says "improved accuracy of the 3G signal strength display."
In Apple's letter, they claim:
"We will issue a free software update within a few weeks that incorporates the corrected formula.
Since this mistake has been present since the original iPhone, this software update will also be available for the iPhone 3GS and iPhone 3G. "
How can they claim the display has been wrong all along when they've already fixed it once?
