I just watched the ipod introduction video available at www.apple.com/iphone. I couldn't help but notice that the slit above the screen, what I had expected to be an ear speaker, was in fact only a proximity / light sensor. At least, that was what I gathered from watching the video from around 12:30 to 15:00. It seems that the only speaker is on the bottom of the phone, near the microphone. I also noticed that, in th keynote, he never makes a private phone call - he's always using speakerphone mode (though that could be just so the call will be picked up by his mic, I realize that). But he was very thorough in his keynote, but he never talks about quiet conversation mode. I can see where the designers might have decided that, in order to keep the phone's size down, they could leave off the ear speaker and expect people to use a bluetooth headset or headphones. So, my question, does anyone know if it is going to be possible to have a private phone conversation using the phone, or will we have to be wearing headphones/bluetooth headset to have that functionality?
