After the 2.3 (Froyo) update this morning, some of my screen lock features are now "Disabled by remote phone administrator". I can't use "None" or "Pattern", and my only options are "PIN" and "Password" to unlock my screen. I was using the pattern option, but can no longer select the feature as it's grayed out.

I am currently forced to use a PIN code to unlock my phone.
I checked my Device administrators and the only one listed is Corporate Sync. I am unable to add/remove/modify any device administrators either. I checked with my IT manager and he has said all the settings are fine, and that all other employees with Droids (1,2,Inc) are working fine on Froyo. I am the only one at my company with an X and this didn't start till this morning.
I am not rooted (nor have I ever been) and I received no errors trying to update this morning. Just wondering if anyone else ran into this issue and/or has a resolution.
Thanks.
