Hi!
That's not completely correct. I wrote a script to dialup a 3G
connection conditionally. The intention for this script was to bring up
a 3g connection during gnome-autostart when a user logs in and after
suspend / resume.
I won't use the autoconnect feature from network-manager at that time.
Dan: I am interesting in automatically reconnect a broken mobile 3G
connection as well ;-)
Attached you can find my script. Hope it will help you!
