I tried it last night as well. I was only there for a few minutes. The wifi did not work, when going to wifi in settings, there was error (I believe that was the wording) under it, the check box was not able to be checked. I then said "ok, lets try the face unlock". It took a while for me to get it to recognize my face, eventually it did. I then tried to unlock my screen with it but I had a crash there as well (insert the "you so ugly, you broke your phone" jokes). The screen started a quick flicker and lost most color. It eventually froze with my picture on screen, and I heard the music as if the phone did a quick reboot. This happened many times when I tried unlocking with facial recognition with Beta 2. I'm sorry I did not test further but I had to get back to a working phone before morning
From what I did see working, it was moving very smooth. I do like the overall feel of the rom.
To answer one of my own questions, I did NOT see the SIP option built into the phone Shucks. I restored back to a working rom before checking to see if auto brightness was included. can anyone comment on it?
