@igor I am not sure what you are referring to here in your query. The phone is stuck in initial boot up after installation. So I would not come to know if my phone's dual sim slots (CDMA + GSM) will work until the initial boot up is successful.
@einstein212 thanks for the heads up! I just got the update and it fixed loads of bugs for me. Turns out I had the updates set to wifi only. I think I did that a while back to prevent things from downloading when I didn't want them to. Makes me feel silly now for doing it seeing how much smoother I've found OTA 3 to be.
