Policies about connection type in mobile device

We need to set up and deploy policies in Afaria 7.0 SP 4 according to connection type (WiFi or 3G data) used by mobile device. We need that if the device is connected to 3G, policies like Lock App Store, Facebook etc, applies. If device is connected to WiFi network different policies should be applied so that it allows access with no restrictions initially created with policies for 3G data connection.
