its not screwing myself over, its just curiosity to see if the official release opens tethering for me, as the GM didnt for O2 IRE
Run this command in your Terminal.app:
curl -s -L http://phobos.apple.com/version | grep -i restore
Find the .ipsw file for your iPHone model (3G = 2,1 and 2G = 1,1) for 2_2_1, open that URL in safari, then option-click the 'check for updates' in iTunes and select the downloaded .ipsw file.

GM = Golden Master = The exact same build that will be released today.
Apple had to start loading a build onto the 3GS ages ago, and that would be the GM build.
People have some wierd theory that apple will change the build before releasing today - which is highly unlikely. They need to chose a GM, and then thoroughly test it, which takes a while.

Gold Master Generally a term that when something is done, you get the gold copy.
It's used alot in software terms to say that it's gone to the CD presses or, in our case, China to have all the new IPhone 3GS' updated with the new software.
