I am probably going to buy a itouch 3rd gen 32gb later this month however i am not sure how the mic stuff works. Does the itouch 3rd gen 8gb have a mic or head phones w/ a mic that can be used for voice commands..? Does itouch 32gb have a mic and does it come in the box? What are the differences btw itouch 3rd gen 8gb and 32 gb..?? Please help..
