V800 Firmware

Does anybody know the latest Firmware revision for the Voda branded
(only available version AFAIK) SE V800 ?

I have R1D003 and it is very unstable:

- Lock-up on playback of Video
- Restart after deleting a contact
- Restart while editing a contact
- Lock-up after hanging up a call
- sudden "Factory reset" after switching the phone off and on again (I
shut the phone off normally, while turning it on again, it showed the
"please wait" progress bar and then all my contacts / ringtones / themes
on the phone memory were gone!)


Is there a "unofficial" Buglist or Firmware Revision list ?


TIA
