Help with ActivateConnection

["Andy Maginnis" <jam smru co uk>]

I am trying to activate my 3 ZTE MF112 using ActivateConnection. I can
successfully connect using the
gui connection manager, however I am trying to script the process so I
can automatically start the 
connection at a set time each day for a short period. I am using NM 0.7
and
Linux op-ubuntu 2.6.31-22-generic #67-Ubuntu SMP Sat Oct 16 19:10:07 UTC
2010 i686 GNU/Linux

I can disconnect the connection if its activated using the gui, I use

dbus-send \
--system \
--print-reply \
--type=method_call \
--dest="org.freedesktop.NetworkManager" \
/org/freedesktop/NetworkManager \
"org.freedesktop.NetworkManager.DeactivateConnection" \
objpath:"/org/freedesktop/NetworkManager/ActiveConnection/16"

However when I try to connect using ActivateConnection

dbus-send \
--system \
--print-reply \
--type=method_call \
--dest="org.freedesktop.NetworkManager" \
/org/freedesktop/NetworkManager \
"org.freedesktop.NetworkManager.ActivateConnection" \
string:"org.freedesktop.NetworkManagerSystemSettings" \
objpath:"/org/freedesktop/NetworkManagerSettings/0" \
objpath:"/org/freedesktop/NetworkManager/Devices/5" \
objpath:"/"

I get the error-
Error org.freedesktop.NetworkManager.ConnectionNotGsm: The connection
was not a GSM connection.

If I use gconftool-2 --dump /system/networking/connections/1 I can see
the settings for my 3g modem. Im not sure
how these are passed to the ActivateConnection command. I am guessing
that the Connection string is wrong
objpath:"/org/freedesktop/NetworkManagerSettings/0" \
but im not sure what to mod it to, i've tried quite a few options but am
getting nowhere.

Does anyone have any suggestions?

Below are the connection settings that I see if I use the GUI to connect
the modem.
