(I have an iPhone but not an iPod and am trying to find answers for a friend.) I know that the iPod's mic and speakers are mostly designed for things like Facetime. Does anyone have experience using an iPod as a phone by which I mean holding it up to your face? Does it pick anything up, or is it worse than when you hold it in front of you for a video-call? Does it work at all, or should I tell anyone wanting to make calls on an iPod to just use the headphones?
