After gaia swtiches using the new web api for setting/getting preferred network type, we should remove the 'ril.radio.preferredNetworkType' setting handler in gecko. Please refer to bug 944225 and bug 946548.

I guess it is safe to remove the 'ril.radio.preferredNetworkType' handler now.

Now that 'ril.radio.preferredNetworkType' is not used anymore, we can't preserve user's selection after power cycle. Some modems will keep this setting, I tested on Buri and it returns the previous selected network type after reboot, but Fugu does not. I am not sure what is the expected behavior? Anyway, the 'ril.radio.preferredNetworkType' setting is broken, it's always the default one on boot-up cause nobody sets it now. So, I think it's safe to remove it. Thank you! :)

Some modems will keep this For preserving user's selection, I think this should be handled in Gaia side (maybe system app?), just like the airplane mode [1]. Thank you.

Comment on attachment 8374823 [details] [diff] [review] Patch, v1 GECKO_PREFERRED_NETWORK_TYPE_DEFAULT seems redundant, we should remove this as well.

Remove GECKO_PREFERRED_NETWORK_TYPE_DEFAULT as well.
