I think this it not a bug itself. When the Sony Ericsson MD300 is inserted, its not recognized as a 3g modem, just as a block devide. To make it to work i need to create the file /etc/udev/rules.d/50-md300modem.rules with the contents:
ACTION!="add", GOTO="3G_End"
BUS=="usb", SYSFS{idProduct}=="d0cf", SYSFS{idVendor}=="0fce",
PROGRAM="/bin/sh -c 'echo 3 > /sys/%p/device/bConfigurationValue'"
LABEL="3G_End"
Then, i just need to restart udev and the modem are correctly recognized.
(i take this trick from the site http://laudecioliveira.org/blog/?p=70).
I don't know if i need to open a new bug, but the network manager only activate this modem in the 'auto' mode, where it choice the band (2G or 3G) automatically, and i can't set it to work only with 3G (i can do this sending the command AT+CFUN=6 to the modem, but NM cannot permit to the user change the modem init strings.
System: i only tested this with ubuntu 9.04 and 8.10 (i386 and amd64).

Thank you for taking the time to report this bug and helping to make Ubuntu better.
Is this bug reproducible with the latest Lucid packages ?
Tanks in advance.
