Auto Join/Login panel missing from WiFi settings tab

Hi, I don't have the option to Auto-Join/Auto-login form my wifi settings.

The way my school wireless network is setup, I need to be able to turn off the settings in order for it to work. I always assumed that the feature was only for IOS 4.1 and above (i've been running 4.0.1 and only upgraded today) but the option is still missing for me.

For reference, here's a screenshot of the two buttons im missing:


This is what I actually see:

I see "Forget my Network" and then the IP Address column. It completely skips out the middle two options.
