There is no single Samsung Galaxy S. There are however quite a few different models, with carriers being more or less heavy-handed with what they want to add or take away from the basic design.
Ranging from a model with no front-facing camera and no (usable) FM radio all the way to a model with a digital TV tuner. All are called Galaxy S (but with a different model suffix). Go figure.

There are a number of different versions for the Galaxy S. Each major carrier in the US seems to have it's own particular version with some differences.
Not feeling so smug now?

I tend to agree with Random Toast. No Firmware upgrade can make the Camera Flash work on the Galaxy S. It does not have one.

Many devices currently have apps that allow users to view youtube videos because of the lack of Flash support. Since 2.2 Froyo will support Flash natively you'll be able to view Youtube videos without needing to use the app. Will that be a better viewing experience? Or, would using the app still be better?

I thought it was just me that spotted the 'flash' comment!

"Some of the bugs listed are pretty fundamental and include flakey Internet access, no support for the built-in camera flash, an inability to lock onto location through wireless triangulation and occasional hiccups with the lock screen."

I'd be surprised if the firmware will ever get the camera flash to work on the Samsung Galaxy S....! ;)
