I just tested the fix from the network-manager ppa and I confirm that it solves the problem. The DNS settings are correctly retrieved by the provider upon connection and added to /etc/resolv.conf .
I have noticed another buggy behavior regarding mobile broadband, but I may should open a new bug for it. When I boot the pc with the HSDPA modem plugged in, while the modem is mounted as cdrom, the NM does not provide an option for mobile broadband connection. If I unplug and the plug it again, the modem is again mounted as cdrom and also NM recognize the device and enables the mobile broadband connection. I have Huawei E220 modem.
