I finally reverted back to the 7/16 23569 Max ROM. Aside from the contact and Facebook bug (patches don't resolve the issue for me), I have a working phone. Would love to use the 7/24 version as saw some enhancements, but the new lock screen was killing me.
I guess corporate ActiveSync device encryption policy strikes again.
I hope NRGZ reverts back to the other lock screen in the next release.
