Like many of you I was disgusted to see what I thought was a serious design flaw with the iPhone 4 hardware and the arrogant response from Apple & Steve Jobs ('just hold it different or use a case'). I even canceled my iPhone 4 pre-order.
However I just did a bunch of testing with two different 3GS iphones in my home. One is running the iOS 3.1.3 and the other is running the iOS 4.0 software. The phones were freshly-rebooted before starting all of these tests.
Using the speedtest.net app against the same server (Tallahasse FL) with the phone in the same spot for each test and each test re-run 5 times for each phone and each position, I came up with the following surprising results:
Control: iPhone 3GS iOS 3.1.3 & iOS 4.0 with or without a case resting on the desk:
iPhone 3GS iOS 3.1.3 & iOS 4.0 without a case held naturally in the left hand as well as held naturally in the right hand:
iPhone 3GS iOS 3.1.3 & iOS 4.0 with a case held naturally in the left hand as well as held naturally in the right hand:
So the point is that, at least for me, the 3GS experiences the 'grip of death' issues (indeed the bars dropped from 4 to 1 whenever I held it in either left or right hand without a case) when held naturally in either left or right hand with no case. Perhaps the silver metal band around the 3GS causes similar antenna issues that people see with the iPhone 4?
And when a case was used there were no issues when held naturally in either the left or right hand.
I have to admit that I thought that problems reported were isolated to the iPhone 4 and are a design flaw - but now I'm not so sure.

Control: iPhone 3GS iOS 3.1.3 & iOS 4.0 with or without a case resting on the desk:
Very low latency and all tests resulted in fast data speeds.
iPhone 3GS iOS 3.1.3 & iOS 4.0 without a case held naturally in the left hand as well as held naturally in the right hand:
3 out of 5 tests did not even complete and resulted in no data connectivity. The successful tests had extremely high latency and low speeds.
iPhone 3GS iOS 3.1.3 & iOS 4.0 with a case held naturally in the left hand as well as held naturally in the right hand:
Longer latency but all tests resulted in very fast data speeds.
