Thoughts
My thoughts:
* The iPhone 4 is definitely more susceptible to attenuation as demonstrated by Anantech - crippling so, I don't think so
* Attenuation does indeed happen on every phone. On testing today, I've discovered that my old Sony Ericsson w800i experiences a drop of 20dB from being on the desk to picking up and holding "naturally", 25dB with a "death grip"
* The bars are demonstrably skewed the wrong way - a 20dB drop would have a devastating effect on this
Despite this coming across as defending Apple, I do believe that it is incredible that they've gone from denying all problems with it, to saying "ooh it's software" while not acknowledging that the aerial design is not the best idea they've ever had. It is rather insulting to say the least - but it's also PR spin.
