Come on guys, all that I want is to access the internal-storage of the phone via USB somehow (even on block-level if not on file-system level).

I'm stuck on the "enter-lock-code" screen when I switch on the phone as touch screen is not working. However when I connect phone via USB to Ubuntu, "lsusb" reports
Bus 002 Device 004: ID 0421:01c7 Nokia Mobile Phones N900 (Storage Mode)

Please. Thanks.
