my iPhone 4 has 351Mb of RAM available right now. How can a "stock" configured 3GS have more RAM available when it only has 256Mb total?

True, if you read my post you'll see I don't mention the iPhone 4 or iPad 2. Only the iPad 1 and iPod Touch 4.
 
Well, so far iOS 5.0 has been running great on my 3GS. I'd say as fast, if not faster than iOS 4.3.3.

Background sync and the new Notifications+Widget bar have been awesome.

That makes me feels better about updating my 3rd gen iPod Touch to iOS 5 now.🙂
 
Ok, I started having weird issues with 5.0 on my 3GS...

- Taking a Screenshot would show Volume for some reason.
- Images shown as thumbnails in the gallery weren't matching up to the correct image (a thumbnail of a picture of a tree would actually be a picture of something else when you tapped it).
- Performance started to really lag with Safari, lots of delays opening programs, etc. basically, out of RAM all the time.
- Mail kept downloading 50 emails over and over and wouldn't display anything.
- Mail kept making iCloud my default account (even though Gmail was made my default).

Basically, just normal "it's beta, not optimized, and generally doesn't work right" stuff. Plus, I was missing all my fun jailbreak apps.

I wiped it and went back to iOS 4.1. Despite what Apple says, you can still go back to an older iOS after installing 5.0.

On a clean boot, free RAM on the 3GS w/ 4.1 hovered around 150 MB (up to 170 MB when you free memory with SBSettings).
On a clean boot, free RAM on the 3GS w/ 4.3.3 hovered around 90 MB.

I can only assume 5.0 had even less RAM available. Besides the new Notifications/Widgets thing, other stuff is designed for devices with more memory. Mail will cache 50-1,000 items (4.x would cache 25-200), the Newsstand widget is _always_ loaded (I didn't see how to turn it off).

I'm looking forward to the next beta. There is still a chance that 5.0 will run as well as 4.3.3. (I don't expect 4.1 or 4.2.1 performance, though.)
 
when opening a game, at least Words With Friends, the volume comes up - does this mean each game has its own volume? or just all games have a different volume then the main?

It's a bug. Taking a screenshot shows volume for me as well.
