DO NOT MERGE - Network type will reflect user's setting

Phone.setPreferredNetworkType will filter the netowrk mode based on
the modem's capability, before sending it to the modem.
As a result Phone.getPreferredNetworkType would not reflect what we
set and the API has been deprecated.

The network mode UI will show the user's preference rather than
what the modem is using.
