This helps explain a lot, especially w/ the bar translation of signal strength and why the results of tapping the bottom left corner is not easily duplicated for everyone. 40% of the signal curve is represented by 5 bars - if you are on the VERY bottom of that curve and tap the bottom left corner, you're going to crater your signal (according to the bars on your phone at least).
I am a big fan of Anandtech. Their technical reviews are easy to understand and very indepth. They were the ones who brought to light the issues with SSD's and even had companies asking him for advice/consulting.
And, as many suspected, it does looks like an inherent flaw in the antenna design. I will believe Anand's evaluation of the issue over the denials and Job's dismissal of it entirely.
AND if you have five bars you could very likely have such a strong signal that you loose 20+ dbm and not see a drop in bars.
After reading this I am firmly of the belief that EVERY iPhone 4 is "flawed" and that the "I have no problem with mine" crowd lives in a strong service area.
Again, I don't think this is something that should stop people from buying and enjoying the phone. But, it is something they should be aware of and something that Apple NEEDS to fix mid-cycle...
