So, this is unacceptable.
I took the 10.1.0.1 via the updater, and it hosed my phone. I couldn't connect to the network, and my phone would activate. So, I ODIN'D back to BLK3, and all was good.
I took the OTA updates, and used this to get back to rooted and unlocked:

So, I downloaded the official CM 10.1.0.3, and installed via recovery. The phone is mobile network state as disconnected, and signal strength of 0dBm 99asu....What is the problem? I can make and receive calls, but cannot get mobile data. I even tried flashing the MF1 AIO.zip and still nothing. This is maddening, and frustrating considering it's listed as stable release.
Any input is appreciated. Thanks.
Go into settings > more > mobile networks. Make sure CDMA subscription is set to RUIM/SIM and system select is Automatic. If either weren't set correctly, set them as I've suggested and reboot or cycle airplane mode and see if it fixes data.
