I checked that and it says the same information as the Phone.Net.get_registration_info method for the com.nokia.phone.net interface path. Thanks anyway!

But it doesn't say which band I'm using (900Mhz/1800MHz).

It would be cool to get the documentation of all methods under Phone.Net. Using d-feet (a D-bus browser) and connecting it to the System Bus doesn't work and it looks there like the Phone.Net is empty.

I also tried using 'dbus-monitor --system interface=Phone.Net,path=/com/nokia/phone/net' and waiting for commands to the interface, but nothing helpful ever showed up.
