Bug Description
"Mobile Broadband" used to work well on Jaunty (network-manager 0.7), over Nokia N85 handset connected over USB.
On Karmic alpha, when I select my mobile network from the network-manager applet, I immediately see an indicator notification "Network disconnected", plus since today's update, the handset also switches off.
modemmanager:
Installed: 0.2.git.
network-manager:
Installed: 0.8~a~git.
modem-manager --debug:

[and the phone is black now]
I see that modemmanager tries to power up the handset which it refuses to do (my guess is, because it's already powered up, isn't it?), gets desperate and turns it off (which is not nice).
Please see what can be done about it.
Thanks!

At least my model (Nokia N85) responds with error to an attempt to turn power on (AT+CFUN=1), and indeed switches off when given "power off" command (AT+CFUN=0). This patch makes the modem manager not try any of these commands on Nokia devices.
