It's because the 3GS has a certain boot rom that makes every jailbreak untethered.
It's still meh for me even with the update. Glad it's gotten better for you!

That's probably it. I don't think we're going to have to wait much longer for 5.1 to be untethered though.

Try typing ##873283# into the dial pad then hit the call button. Wait a minute or so and your PRL should be updated. Mine is at 60687.
