How to make sure I'm not using any 3G data?

I just got an iPhone for the first time, let alone any kind of smart phone. I did not sign up for much data, when my phone is on, what can I do to make sure my phone is not using the 3G data? I know I can use Wi-Fi, but when I'm out of range of that is there anything I should look for to keep it from doing anything. I have been opening the safari browser and making sure all of the internet windows are closed, anything else?

We already tried to turn it in, that was a no go.
