I am not sure that what you want is actually possible... I have never
heard of running 2 networkmanagers at the same time.

You might want to try the gnome networkmanager that is said to be much
better at dealing with mobile internet. Look for network-manager-gnome.
Uninstall Wicd and network-manager-kde if they are not removed by
network-manager-gnome. You will find a new systray applet and in that
there is mobile internet etc.
