Upgrading my Samsung Galaxy S to Froyo

I went through the ordeal of installing Samsung Kies, their mobile/player manager and getting it to recognize my phone, only to find out that the custom firmware on my phone installed during a visit to Samsung Service Center couldn't offer an upgrade through Kies.

But thanks to the wonderful internet, there're other ways to flash the ROM to the latest and greatest. The links below provide a very clear step by step instructions.
