File tranfert problem with Sony Ericsson C702 phone

In ubuntu 8.10 , there are some problems regarding file transfert with my Sony Ericsson C702 cell phone through USB cable. If the phone is put in "USB mass storage mode" I have the following kernel logs when the phone is plugged in:

And no new icon appears in nautilus!!!!!
Impossible to mount the new usb mass storage device.

If the phone is put in "Phone mode" I have the following kernel logs when the phone is plugged in:

The corresponding icons appears but the free memory from the card (M2) ist wrong. The memory card isn't correct recognise. I thing that it's show the free memory from the phone and attribute it to the memory card too.
