Convert your Sony Ericsson M600 to W950

Just a while back I posted about the possibility of converting the K800 to K810, now somone claims that it's possible to convert the M600 to W950. Filip from semania.cz announced that he has succeeded in flashing W950 firmware onto his M600. He provided all the pics from above to prove his claim and a video clip. However, he didn't reveal how he did it or provide any other info. I am curious to know how the phone functions...since the W950 is a bit different than the M600 in hardware. Maybe this is all a hoax?
