just a quick question, i have seen vids on the unboxing, speed test, and some reviews of the Iphone3gS. but i still don't see anyone doing vid doing bout the headphones as i can tell theres a volume up and down toggle there, and i wanted to know whether the mic works for the voice control feature? does it act the same way as ipod shuffle's headphone? or is it still the same so the button in between the volume controls is to answer calls/ plays music? if it does acts like ipod shuffle, that means the button is to activate voice control, this is actually what i pictured when watching the guided tour for iphone3gS, he practically mentioned 'pressing the headphones'
