[Q] Is this bootloader information correct?

http://forum.xda-developers.com – Bootloaders... 1. i9000 was launched with Éclair so the bootloader was of course an Éclair bootloader? 2. People who upgraded to Gingerbread from Éclair without upgrading via Kies had to flash a Gingerbread bootloader via Odin? 3. Flashing ANY rom wont change the bootloader? Like CyanogenMod. 4. I'm running CM9... does that mean I have an Ice Cream Sandwich bootloader now? I'm so confused by different things I've read off the net... please please someone put my mind to rest! I'm writing a few BIG guides and kinda came unstuck when I got to this subject lol. (HowTos)
