So, if you've moved from "not connected" to "connected" with the attribute set to "wifi", and get a message from the 3G module, you can just ignore that.

Or am I missing something here?
will this satisfy your suggestion:
Code:
#! /bin/sh
# /etc/openvpn/dbus.openvpn
# This script is invoked by dbus-scripts when connection changes
# state.
LOG=/var/log/dbus.openvpn.log
STATUS_FILE=/var/log/dbus.openvpn-status
DAEMON="/etc/init.d/openvpn"
NAME="dbusScriptsOpenvpn"
DESC="Sipn openvpn deam up and down by dbus-scripts"
CONN_STATE=/etc/openvpn/connected
# Connection serial in saved connection database 
CONN_ID=$5
#$6 is GPRS or WLAN_INFRA or WLAN_ADHOC
TYPE=$6
STATUS=$7

        Count=0                                        
        for arg ; do                                   
                Count=$(( $Count + 1 ))                
                echo "Parameter $Count = '$arg'" >>$LOG
        done                                           
        test -f $DAEMON || exit 0                      

#current connection state is "connected"
if test -f $CONN_STATE ; then
	if test "x$STATUS" = "xCONNECTED" ; then

	elif test "x$STATUS" = "xIDLE" ; then

	echo .
elif test "x$STATUS" = "xCONNECTING" -o "x$STATUS" = "xDISCONNECTING" ; then
	echo .
