Android 3G/2G control API?

Question

On Android settings, under Wireless controls->Mobile networks there is a setting "Use only 2G networks".

In the Android SDK reference, under android.telephony.TelephonyManager, there doesn't seem to be anything to control the network type.

What APIs does this setting actually call?

Answer 1

It appears to call com.android.internal.telephony.Phone.setPreferredNetworkType(). Since it is "internal", it isn't available to applications via the SDK.
