That's what I thought, but there's nothing there for some reason. I haven't messed with that setting in a long time. It may be due to my exchange email account on my phone, because my work's exchange settings force specific security features to be enabled on the phone; such as using a pin code to unlock the phone. I'm really not certain though. I just removed my exchange account and rebooted the phone, and for some reason the security features are still there and it won't let me change the unlock method even after deleting the exchange account.
