I can confirm that it doesn't work with AOSP contacts on this rom. I flashed back to stock contacts and did get the menu, so it isn't the rom. Mine was already set to Rev A.
So far this morning I've gone between 3G and nothing. This is with the CDMA+LTE/Evdo Auto setting and the leaked radio.
Enabled? Did you activate your phone in a 3G only area? If so I think this would explain why your phone was on this setting
