What has happened to Samfirmware.com!!!
The part of Samfirmware.com where you were able to download all stock firmware has now changed to SamMobile.com. I think the firmware is not available till November, instead of downloading firmware there will soon be a firmware tool?
Still this is not the end for those of you who need to download the firmware versions.
BarosanuXXL has a thread which lists all the stock firmware releases for the i9000, so far:
Official firmwares for Samsung Galaxy S I9000 - Download
The firmware section is available:
SGSI (i9000) - Stock & Custom Firmwares
SGSII (i9100) - Stock & Custom Firmwares
