The following steps works for me:
1. Jaibreak the phone (via http://jailbreakme.com)
2. Install openssh from cydia
3. ssh to the phone
4. change DBVersion to 4 in the /system/library/lockdown/Checkpoint.xml
5. Generated HashInfo following the link http://ihash.marcansoft.com/
6. copy HashInfo to the folder /var/mobile/Media/iTunes_Control/Device/
7. Reboot the phone
8. Mounted device automatically using Ubuntu Natty (libmobiledevice, ifuse and so on already installed)
9. Sync using Banshee
