A few days ago Canon released Firmware version 1.0.4 for the EOS 20D DSLR. Yesterday the firmware was pulled from their BeBit website, with only the words “Firmware update service is not available temporarily” left to show that the firmware was ever there. It seems that some people have installed the new firmware and experienced problems (like the camera not actually working) - let me know if you were one of them.
