Voice Control On iPhone 2G? [video]

So it appears that some hackers ( french?!?! ) managed to get Voice Control on iPhone 2G ( EDGE ). So, many other hackers tried to bring Voice Control to the iPhone 3G, but they failed because they got errors of hardware incompatibility.

Even if you are not tech-savvy , based on the previous statement, you can tell that this function is not only based on software but on hardware as well. Now, since the function couldnt be ported to the iPhone 3G, and this video is really not clear ( and my french is not that good, so i couldnt follow exactly what that dude was saying ) , i call this a big fat fake. What do you think?
