How with all the research apple and att must have done into dropped calls that they didn't figure out the bars were a misrepresentation of true signal strength?
No no no. They did it on PURPOSE. Years ago.
It's so people who lived in houses that used to say 2 bars will now say 5 bars. Wheee! Everyone's happy!
In other words, they decided that lying to you would make you happier.
But in the end it simply made the iPhone 4's reception problems (which are real) look even bigger than they really were. So Apple's being punished for trying to cheat the system.
Karma
This would have been a MUCH smaller deal if people knew their real reception. It would exist, but there would be less threads about it than about smashes glass backs.
