The Iphone 3G unblocking was announced by Dev-Team and widely spread by ENGADGET.
In just a few hours, the news was known worldwide, but it seems that the famous yellowsn0w firmware is not finished yet.

It would run only with the v2.2 firmware (probably tomorrow, Apple will update at v2.3)

GIZMODO published a poll about the functioning of the new "unlock" firmware: only for 23% of the voters the software works!

I think I'll wait a little bit more before I'll burn my iPhone. What do you think?
