Although it's worth noting that Apple sometimes has a very weird definition of "Gold Master". The latest Xcode 4 GM, for example, is pretty much just another beta version. It's not production ready at all.
iOS GMs have always been ready to ship, minus a few 3rd-party apps and last minute exploits(JBs). If they are throwing GM designator on anything that isn't usable than I'm severely disappointed.
You'll also be able to download the latest 10.6.7 build if you'd like.
