Scenario: you are on the road and staying at a hotel offering free wifi. You search for the network on your BB, select it, and connect; but the wifi badge never goes white and you are not truly connected to BIS. Stumped, you decide to check with your laptop and discover it has a disclaimer screen that you simply have to click the I Agree button for, and away you go.
However, you never see such a screen on the BB. I think this is what the OP is asking and I'd like to know too.
