I am sure I am not the only one having an issue with this, I upgraded my iPhone 3GS to 4.2.1 factory fresh install and it will connect to my router but will not let me load anything from then on. It says I;m connected but in reality I have no connectivity. anyone else experience this? I have searched the forums and Couldn't seem to find something related (maybe I'm blind) to this. I'd like to get this sorted and would also like to avoid re-installing my iOS again, thanks for your speedy replies.
