It's fairly simple to understand what Apple is trying to say. When you hold a phone a specific way, the signal can drop. This is consistent with almost all the testing we've seen. The only reason why the iPhone 4's antenna is getting so much flak is because Apple made a huge mistake.
They tried to tell people their antenna was more awesome.
That was a mistake because all antenna's suffer from signal attenuation under specific circumstances. If you tell people something is awesome, they wont just take your word for it. A lot of people were expecting better antenna performance. No matter how well the phone is designed, some people are going to have signal issues. Basically, Apple made a stupid claim they could never back up.
For some people the antenna performance improved...
For some people it was unchanged...
...and for some it was drastically reduced. Those people got pissed off. They got more pissed off because they were told the antenna was supposed to be better.
Until I heard about this whole death grip thing I never noticed that the signal on my 3GS drops drastically when I hold it outside the case. It just so happens the way I hold it is just like in the picture on Apple's new webpage. I'm holding it in a specific way that causes signal loss.
The only way I never noticed it before was because I never thought about it. I've had dropped calls on my 3GS. Probably some due to this issue but I never would have thought that it was because I was holding it wrong. Also I have a case which reduces the problem drastically.
Of course testing shows the iPhone 4 dropping more signal than other phones, because it had more signal to begin with. Anandtech testing shows this a little. The more exposed the antenna is, the more signal gain. Apple designed the new antenna to work this way. The tests show that too. Adding a case also drops the signal gain on any phone. However, adding a case also helps with attenuation because it insulates the antenna more. Phones without exposed antennas have a little less attenuation in some cases. Call it a design quirk or a flaw...
iPhone 4's have more signal gain, at the cost of being more susceptible to attenuation.
Thats it.
So I learned something today... I learned that holding any phone wrong can mess with the signal. I also learned that its a good idea to use a case on my iPhone because I happen to hold it differently. I also learned that its stupid to tell people that something is awesome unless I can really be 100% sure that it is (especially if its an antenna).
