For those people having problems with their Wifi since installing 2.0, you may want to try doing a Network Setting Reset on your Touch. I know it can be a pain to type in your password again, but it seems to have helped me.
I live in the city, and before 2.0 I would see 10-20 available networks when Wifi was activated. Since 2.0, I have noticed a gradual decrease in the amount available and the signal from my own network has been getting weaker. It got to the point a few hours ago where there were only 2 available (mine and someone who has an open network with a strong signal) and web pages either were extremely slow to load, or didn't load at all. Since resetting, everything seems to be back to normal. I'm not sure how long this will last as it seems as if there is a slow drain of the Wifi power (can't think of another way to explain it).
