froyo on the htc dream.

Hey guys. So I was on a website and they were talking about an oficial update for the htc dream so u can update it to froyo. I,ve been checking out videos on youtube and it seems pretty cool. I was wondering if anyone can give me the link for the update. Im with rogers and my dream firmware is 2.0. If there's not an official can i get froyo onto my phone? Thanks!
I also finding same stuff but not much idea about it if any one have then please mention here I am equally eager to see this one because I tried to found many time but I am not success in it.
