YES!! That's it precisely. I say nothing is going on. The burden of proof is upon those that say there is an issue.... and so far
all of the presented evidence is anecdotal, isolated, incomplete, fractured and thus meaningless
Again, that makes no sense. In any new situation the information is 'anecdotal, isolated, incomplete, fractured.' Shoot HIV information was that way for about 5 years before it became 'fact'.
That initial information is this way does not make it 'meaningless', the analysis just has to be smart enough to separate the wheat from the chaff, and to deduce what situation would explain the incoming data.
What do we know:
We know that people who have never had a drop call problem before with any previous version of the iPhone are reporting such in large numbers. These dropped calls are very often happening in exactly the same locations that they weren't being dropped before.
We know that holding the phone in a very specific way that effectively doesn't change the adjacent mass to phone profile significantly is having significant effects on both displayed signal strength, but more importantly the ability to continue on an existing call. make a call with a very small area of the phone not touching skin and the call and bars are fine, move a millimeter or two so that the skin is now touching the phone only in a tiny additional area and the bars drop to zero and the phone loses the call. This behavior is reproducible and consistent in that location.
We know that shorting an antenna is not the same as body mass attenuation of signal (just simple physics there). Hopefully we can agree that body mass attenuation of signal when using cell phones is normal, being able to short out the antenna with normal use is not.
A reasonable person would conclude that something new is going on. Further we know that the base handling of how the 3G radio worked with cell towers was rewritten with a fundamentally different objective for iOS 4.
Again, pretending that it is just pure serendipity that suddenly all these people losing calls just 'happen' to have new iPhone 4s is just such a stretch.
Now your concern seems to be this is mass hysteria caused by a Gizmodo article and that people are fretting about merely 'losing bars' when we all know that grabbing any cell phone in marginal areas makes you lose bars. yes, that is an issue but even if Gizmodo isn't technically right what they are talking about is part of what's really going on. But we aren't talking about what they are - its not about merely 'dropped bars' its about 'dropped calls'.
I'm not fooled by things like that, I don't even read Gizmodo. I am very objective - my new iPhone 4 is losing calls at my home from the moment I started using it, where I have used an iPhone as my primary communication link for years and never had this problem. Further, my problem is solved by putting the 4 in an old silicone Encase for the 3GS.
Just because 'studies' haven't been done yet doesn't make the information that is available 'meaningless' - studies are eventually done expressly because of the existence of this kind of information.
