Samsung has baked a new firmware, JV9, for Galaxy S. This latest firmware upgrades the Galaxy S to android 2.3.3.
Kies only recognise official firmware versions, i.e. those with telco modifications (XSO). Local firmware w/o telco mod (XSP version) is not eligible for the upgrade still.
Check out this page to switch to XSO

JV9 brings mainly comestic changes, following is a list of changes i have observed so far,
- standard android icons on the status bar, instead of Samsung typical blue icons
- new icons on the notifications tray
- alphabet bar in phonebook as been reverted to the full list
- daily briefing widget has been broken into 4 seperate widgets now
- wallpaper picker now has 2 size templates to choose from
- android text selection cursor has replaced the samsung cursor
- "ask on connection" in USB settings has been removed
- OTA Software Update has been built into the firmware now
First run of the GPS seems to give a slightly better results too. Runkeeper manages to track my position accurately for most part of the trip. Somewhat puzzling is that both readings suggested that I have crossed the road along Tampines Central 2, which I have not.
All in all, JV9 seems to be a nice upgrade. Onto gingerbread now.
