Comment 8 for bug 509738

Update to the latest modemmanager and network-manager on Lucid:

ii modemmanager 0.2.git.201001 D-Bus service for managing modems
Version: 0.2.git.20100119t230703.ed885b7-0ubuntu1~nmt1~jaunty

ii network-manage 0.8~rc2-0ubunt network management framework daemon
Version: 0.8~rc2-0ubuntu1

It seems the PIN is no longer served to the simcard:

Jan 21 11:37:18 lvm-laptop NetworkManager: <WARN> stage1_enable_done(): GSM modem enable failed: (32) SIM PIN required

Output in /var/log/syslog is attached.
