It would be easier for people just to explain indexing of the first core starts at 0 and the 4th core is at 3.

Objective-C sits on top of C. C sits on top of Assembly. Machine translated code doesn't speak to the hardware as Objective-C or C.
If by this time you actually believe the rumor of an iPad 4 later this year, I have an iPad 5 and and iPhone 7 I'd like to sell you.
Sure they do. Go to www.apple.com, and you'll seem them touting the dual core A5 in the 4S right on the front page. Click on iPhone, then specs, and you'll see all kinds of info Joe Consumer doesn't care about...publicized.

Doubt they'll need to. Just look at the Transformer Prime. It's a quad core device running at 1.3Ghz, and it's just about able to match the iPad2's battery life. I'm sure Apple can do the same.

I can see the native apps being blindingly fast but it almost seems that some apps run slower on the 4S than on the 4 because the apps are only developed for single core use and the cpu speed is actually lower on the 4S. So it seems that development on 3rd party apps wouldn't be there except big name developers. A quad-core would have to be under clocked lower than the 8XXMHZ than the 4S is clocked at to save battery and prevent heat damage.
Then again I could be imagining things
Trolling much?
One of the things Apple cares about is how well the software and hardware integrate. A quad-core processor would allow for lower clock speed which inturn would make the software more efficient and generate less heat which is better for battery life. Apple likes to be about reducing so maybe there quad-core will require less power which again will help battery life.
Consumers care about specs, also Apple's development team cares about specs when they are actually building the phones, that is what we are seeing.
I didn't say they don't publicize any specs. I wrote that they didn't publicize many specs.
Note carefully that Apple does not tell the CPU frequency, nor how much RAM the iPhone contains. They don't mention what version ARM architecture the A5 chip has, nor the graphics subsystem name.
A minority maybe, the majority are rather more into the glass bit on the front and what appears on it.
Yeah, Apple doesn't care about specs, which is why the 4S has the most powerful mobile-phone GPU on the market which trashes almost everything else.
Apple simply not idiotic enough to base its advertising on specs, but it uses the most ideal and optimized hardware possible for the task at hand. It's not idiotic enough to believe most consumers understand or even give a crap about those numbers.
Indeed, what software do the screenshots depict? Some disassembler? Or simply source files in assembly?
Objective-C is a thin layer on top of the C programming language. A compiler/linker converts the high level Objective-C/C language to machine code for the target processor. This is what you are looking at.

Poor example, Tegra 3 is a 5 core CPU. The 5th core is a low power/speed core that handles most of the work. (basically I am saying that Tegra 3 cheats)
Um, the 4 and 4S are both clocked at 800Mhz, the 4S architecture is faster than the 4. Clock for clock. How is the 4S slower?
can someone please register my udid
i am willing to pay
That's not allowed, mate. Apple kick folk off the program for that.
Not necessarily. The iPhone 4 is in terms of pure graphical power not anymore powerful than the iPhone 3GS, yet it needs to push four times as many pixels.
From what I understand, the tri-core ARM is simply a quad-core that as one of the core disabled because there is a defect in one of the cores. It works pretty fine as a tri-core processor but not as a quad-core.
