Maybe I "just don't get it" but I've had problems logging into free airport WiFi. Ferinstance, I look in my iPhone and see the free airport network. I click on it and it more often than not has a "login" screen where it asks for you to accept terms. Often though that's not what happens. Sometimes I can just "try" to open my web browser Safari and I'll get the login screen. Other times I'll get the message "you are not connected to the internet." I'd like to know what the best sure fire way is to connect to WiFi. Is it to attempt to open a browser or just go into settings to networks and attempt to join there?

TIA
