New cellular network types

New cellular network types (cellular data registration states) are added.

When cellular network type is "IWLAN" and the phone is on, call is VoWifi.
The only exception is when the following conditions hold
- Verizon sim card
- 1x coverage only
- Wifi is connected
In this case calls go over cellular (cdma 1x).
