Why there is no thread that contain sony ericsson firmware?

I think there are no firmware for sony...
I mean direct download firmwares...
Still if there are any pls post them and we will make a section for it...

i'm so sad about that... i don't have any too..
but i ever heard that M600i can be flashed to W950 and there are two firmware at there, but there is no the download link.
i wonder where they got that firmware?
