The 3GS never/does not come in an 8GB model. Just 16/32. The 3G came in 8 though, but thats long gone.
Incorrect. It's launching as the new low cost entry point for an iPhone.

I am curious how many of those clamoring for 512 MB can actually provide a usage case where they need it or they're just asking for bigger numbers for the sake of them.
I seriously can't imagine Steve omitting this from the keynote if true.
But if it *was* 512 that'd be super news and the last push needed to upgrade.

Likely almost the exact same. It's the peripheral I/O support type chips that are likely different. It will also have its own special power management chip. The reason that the A4 is 1 GHz vs. 3GS's speed is that it's manufactured on a 45 nm process compared to the 65 nm process or the 3GS. This allows it to be clocked higher.
The fact that Steve did'nt say 1ghz A4, really makes me think it is clocked down.
I believe the 3gs is also a cortex a8 generation code, so mhz for mhz should be near enough same, excepting perhaps for any tweaks in size of cache and such.
The iPhone 3GS was all about speed. Thats why they mentioned it then. Clock speed and RAM really doesn't matter what so ever on a phone so why fuss about it?
You can run the iPhone OS just fine on what it already has.
Excuse me, everyone, what is Ram?
I'm working on an infographic that states the new iPhone 4 includes a pancake griddle. Stay tuned for proof of this feature!
Ding Ding Ding. We have a winner. The 45nm process is more power efficient than the 65nm, allowing Apple to clock the A4 higher while maintaining battery life.
If it makes you feel better, Apple has never confirmed the A4 runs at 1GHz on the iPad. Apple never talks specs. They didn't on the iPad, the didn't on the 3GS, and they won't on the iPhone 4. Doesn't mean the A4 is underclocked.
A4 is custom silicone. Check the wiki page for differences from traditional ARM architecture.

The A4 has distinct differences that allow it to run at a higher clock rate than the regular A8 core. The SoC Apple has setup on the A4 make it significantly more efficient.
One observation I'd like to note, all of the tech sites report the new iPhone is as fast as the iPad in their hands-on previews. Take that for what you will, but sounds like 1GHz to me.

http://en.wikipedia.org/wiki/RAM
Random Access Memory (RAM) provides space for your computer to read and write data to be accessed by the CPU (central processing unit). When people refer to a computer's memory, they usually mean its RAM.
If you add more RAM to your computer, you reduce the number of times your CPU must read data from your hard disk. This usually allows your computer to work considerably faster, as RAM is many times faster than a hard disk.
Even if the memory is the same as the 3GS, and the clock speed is less than 1GHz, I think we're going to see performance increases.
Why? Because this is Apple's chip, using Apple's hardware, running Apple's software. That's what sets the entire lineup of Apple products apart from everything else. They engineer, design, and produce [most of it] using their own specifications. That's part of their entire product philosophy.
So the previous processors in the last iPhones did the job, but now they've got something custom made to exactly what they want, and their software is written for the hardware they produce. They have full control over it, which is something other companies can't quite claim yet.
Not to go too far on a tangent, but think about the PC world [i'm a PC guy btw, got my first mac last year]. I reinstall Windows, then I have to go and download drivers from multiple sites to make the hardware work, then go to another place to get the software that does what I want. All from different vendors or companies. Now think about Apple. You install OSX, there are no drivers to install [unless you have custom equipment], and Apple produces an array of utilities that can accomplish what most people want, written specifically for OSX so it runs efficiently.
I may be overhyping what I've read about the A4 chip, but based on what I've read, if you designed the silicone, and you wrote the software which operates on it, it's going to be pretty darned efficient.. to the point where doubling the memory and upping the core speed may not be required.

Sure. Preloading Safari tabs for transient travel through areas with no connection. I'm lucky if I can keep 3 open without it needing to reload, or crash while switching even on the 3GS.
When I had a jailbroken 3G iPhone I could never keep a backgrounded audio stream open for long since it'd crash due to lack of RAM. The 3GS made all the difference in the world, but as I said above doesn't stand up as well when Safari enters the picture.
