I wouldnt say that, cause the 4 is nowhere near that kind of speed increase.
As you can see here, the 3GS and the 4 are cut from the same cloth. Of course the 4 is marginally faster, its clocked a little higher.

First of all I need to know - do you own both a 3GS and an iPhone4?
First you need to know that the speed on the 3GS is 600MHz not 733 as you stated, the iphone 4 is running at 1Ghz now math has always come pretty good to me and I actually gave you an example that was favourable to your argument. You stated my comparison was to big a boost from 2.4 to 3.0 when 600 to 1000 is nearly double?? I think someone is now clutching at straws, I think someone is a little upset that they got a 3GS under the xmas tree instead of a 4. You are also forgetting the fact of the large RAM increase.
"Even though iPhone 4 is rendering 4 times the pixels on its new, high resolution Retina display, it does more faster than the recent iPhone 3Gs! iPhone 4 consistently loads and renders web pages faster than the snappy iPhone 3Gs.
Part of the speed increase is due to the faster Apple A4 processor (like the iPad), another factor is the new HSUPA support in iPhone 4. That means in supported areas, iPhone 4 will have up to 60% faster downloads and up to 500% faster uploads. This test result is likely to have reflected both these factors."

To note to people saying reception is not as good I say please show me comparable tests because in sections of my building at work on the 3G and the 3GS I would loose all signal or drop to edge from 3G, once I got the iphone 4 I would have 2 bars of 3G in those locations, same telco.
At the end of the day your argument holds nothing... sorry.
