First of all Nice layout of the thread, it's presented well and easy to read, a little more screenshots could be useful for the all the Beginners.
Secondly, I don't think this is of use anymore because the Sony Removed the "Install other OS" function from the 1st, 2nd and 3rd generation PS3's, Sony also doesn't allow people to downgrade their PS3's to an earlier update.
Props for finding the time to post the thread, but relevance to the current update and PS3 firmware are none, the only people who would be able to do this would be those who didn't update to Firmware 3.30 or Earlier
