Maybe I'm missing something, but if the problem is just the software that displays the number of bars, why does the iPhone 4 drop more bars than other iPhones which are running the same software?
It seems like there's still a problem with the antenna design that was just made more obvious by the software.
I think what's obviously going on is that Apple was deliberately displaying more bars in areas where there was week signal in an act of deception to try and make up for AT&T's crappy network.
