Have fun waiting.....you knew what you were getting into.

Doesn't bother me. My phone is still on 5.13. It is my dads phone and he doesn't care that much other than the GPS not working. It's not like his phone is ruined.:p
 
Basebands cannot be downgraded on an iPhone 3GS, as far as I know.

And as far as having 6.15.00 goes, I don't really see anything wrong with it. I own 4 iPhone 3GS devices right now with one running on 6.15 and used to own a 3G running on 6.15 and experienced no problems. I already have an awesome GPS anyway so losing that wasn't really an issue for me.
