I don't have an iPhone, but I'm looking into it. I saw someone in a restaurant yesterday, and he had headphones on and was (I presume) listening to music from his iPhone. The phone rang and he just picked it up and started talking. What I don't understand is that I thought you could only use headphones that also had a microphone on the cord. It appeared to me that he was talking directly to the iPhone microphone while still using the headphones. The older cheap phones would disable the microphone as soon as you pluged into the headphone jack. When did this change? Is this feature unique to iPhone or is it now common on newer phones to still be able to use the phone microphone while listening via the headphones? Would that mean an older style headphone with microphone wouldn't work with an iPhone? Thanks for any assistance.
