Well I have found a problem with the two links. The direct file from jacekowski is bigger than the file from the IRC rapidshare link (which was zipped).
The IRC file is around 6 MB like the original file, so maybe it's a tweakflashed one.
I am installing it right now. Is there a way to tell the difference?

UPDATE:
Original file is 6732516 bytes
new file is 6723876 bytes which is actually a bit smaller, so I really don't think it's flash 10.1 Usually new functionality means bigger files. Going to test it either way.
