Why flash it rather than using KIES for official update?
One thing I realized : Original firmware is not to my liking, lag and slow. I want my phone to be fast!
I have been doing this for a few friends and a few others via email. I think it will be more beneficial for me to post it up as a reference to all. (Some friends willing to travel 300km to meet me for this).
Kudos to Justin Tan (Photog and LancerGT brother) who train me about ODIN over MSN...

Let's start with tools you need:
- Windows PC/Notebook (For Odin)
- Your SGS (Samsung Galaxy S) cable
- Odin 1.3 (and above) - This is your flashing tool
- A firmware of your choice (For this I use : Froyo 2.2.1 JPY)
