Safari is not allocated all 512MB of RAM. The OS requires part of it, and your other applications require part of it. If you have ever bothered to look at Safari's memory usage on Mac, you'd know it can easily consume 512MB of memory all on it's own.
Before you assert that I'm wrong, you should be certain of that.
All iOS updates contain the entire operating system. Apple doesn't do small updates (not in their vocabulary!).

I wonder what the last minute change to the 3GS was - 8C148a was never seeded to Devs
Oh, ok. I only posted it because the MacRumors article makes it seem like only Apple TV is getting the 4.2.1 update, and the article's screenshot only shows "4.2" 😕

They do patches for Mac OS.
But since all iOS devices are synced.. it just makes more sense to flash their firmware entirely. It's a much simpler process than trying to set up a framework for delta updates, and it avoids potential corruption issues that delta updates can cause.
I tried last night printing to an HP printer on an Airport Extreme and my 4.2.1 GM was not able to see any printers.
I've checked Safari's memory usage using the developer tools and it doesn't use anywhere near the full amount of RAM, nor is anything else using so much RAM that Safari couldn't take advantage of it.
Besides, web pages are incredibly small. RAM usage should not be an issue with this.
Incorrect.
There was a WiFi bug in:
Public 3.2
Beta 4.0 through Beta 4.2
4.2 GM #1
4.2 GM #1
and
4.2.1 GM which is the same the public build just now released.
So, again, I ask iPad WiFi bug? It has not been corrected as far as I can see, so I'm looking for others to weigh in.

I don't see an option or the new text tones. 😕
I'm using an iPhone 3Gs. I don't know if this is why or not.
This is weird...
I get the notification that my 3G can be updated to 4.2, but when I click "Update" I get an error that iTunes (yes, iTunes) is already updated to the latest version, 9.2. I'm clicking the update button on the iPhone screen next to the "new version available" message. What the heck?
Anyone else getting this bug?

Pick a web page, load it in Safari for Mac. It should instantly consume between 10 and 50MB of memory. As I mentioned earlier, I guarantee you that Safari doesn't have full access to the memory.
Why?
Other applications and multi-tasked applications would ultimately have to forfeit their state to allow Safari to have more memory. I'd be surprised if Safari has access to any more than 128MB of memory.
I just loaded two pages as a test:
A graphic-heavy non-flash site consumed 20MB of memory, a graphic-heavy flash site consumed 42MB. Safari for iPhone isn't going to consume much less, if any, memory than Safari desktop does -- excepting the absence of flash.

I thought it was funny when I upgraded to 4.2.1 GM that my iBlanks remained on the screen. Sadly that was all. Same thing with my prior 3G. Had the jailbreak showing the battery percentage before it became officially supported and when I removed jailbreak, my percentage still showed as well as the option to turn it on and off.
