It isnt software related, its hardward that has been added that means its cant be implemented on prior models. Although we know technically the 3g can record video and voice control.
What kind of extra hardware is needed to do voice control besides a microphone and software?

Although, to play devil's advocate, I was using Microsoft Voice Command on my Cingular 2125 over two years ago and it was pretty responsive. 200Mhz Texas Instruments OMAP850 processor. I think the V1/3G trumps that pretty handily.
