usb - File Transfer: How to transfer files betwen my Xperia Neo (Android 2.3) and Kubuntu Linux?

I have bought a Xperia Neo which runs Android 2.3 and I'm running Kubuntu Linux on my Laptop.

I just connected the Phone using a USB Cable and set it to Mass Storage Mode. I expected to have the phone SD card in my devices list, so I can mount it and use it as a file storage. But there were no device added.

A few Googling led me to some Microsft Applications, (Activesync, etc.). Does it mean I cannot connect to my phone's SD Card in Linux?

Should I really use Windows for such a simple task, Tranfering files using a USB Cable?!

Note

With the help of @onik I tried to mount the SD card manually and here is the result: in Mass Storage Mode

takpar@skyspace:/media$ sudo mount -t vfat /dev/sdb /media/android/
mount: no medium found on /dev/sdb

takpar@skyspace:/media$ sudo mount /dev/sdb /media/android/
mount: /dev/sdb: unknown device

takpar@skyspace:/media$ sudo mount -t ntfs /dev/sdb /media/android/
Error opening '/dev/sdb': No medium found
Failed to mount '/dev/sdb': No medium found

and in Media Mode there would be no /dev/dsb anymore. But a window opens with url: camera:/MTP Device@usb:001,021/ and empty content.
