I agree.
Apple didn't release any of the situational information about their supposed "tests". They didn't tell us where the tests were conducted, when the tests were conducted, etc. If they really wanted their videos to be believable, they should have gone to multiple locations around the world and conducted the tests with each phone at the same locations. Then, they should've told everyone where the locations were so their tests could be tried by others.
Their little "experiments" showed nothing of substance because in order for a hypothesis to be proven (all smartphones have the same the same attenuation/call drop problems that the iPhone 4 has), it has to able to be replicated without fail by someone other than Apple.
There are no big stories of people clammering to return their Droid Xs, n97s, HTC handsets, or Samsung handsets because of dropped calls because, quite frankly, those phones don't drop calls like the iPhone 4. Sure, those phones each have their weak points and problems, but for Apple to assert that those phones share the same weaknesses that the iPhone 4 has (dropping calls) is absurd.
Don't even get me started on the iPhone 4s problems with the proximity sensor. I'm waiting to see if the same PR "geniuses" that released the videos supposedly showing the competition's phones having signal attenuation problems will release another round of videos showing that other smartphones have proximity sensor problems, too.
I haven't had a single proximity sensor problem (or dropped call, I might add) on my Droid X since I purchased the phone almost three weeks ago. I had one or both of those problems with nearly all of the hundreds of calls I made in the three weeks I had the iPhone 4. That's the bottom line for me. And here I sit, able to make crystal clear calls without hanging up on people with my cheek while people are still posting on Apple's discussion boards wondering when Apple will release iOS 4.1--which might potentially fix the proximity sensor problem they're having--no guarantees.
