Paul: IMHO, this bug is just a result of the move of the switching functionality from udev (modem-modeswitch) to usb-modeswitch.
Installing lucid's usb-modeswitch seems to solve all the reported issues (without hand-tweaking needed) and the only remaining issue that you seem to mention is that usb-modeswitch is not included by default on Lucid. This is NOT a bug in usb-modeswitch. [In Debian, network-manager recommends modemmanager, which recommends usb-modeswitch, so usb-modeswitch gets installed with network-manager.]
Therefor, if Angel can confirm that installing lucid's usb-modeswitch solves his issue, this bug can be closed (with whatever resolution).
