I bought my 16GB iPhone last night. I am in love with everything except that I can't hear when talking to someone! The speaker volume is fine, headset volume fine, but the ear speaker to talk like a normal phone is so incredibly low I can barely hear the person in a silent room and not at all when there is any noise around. I have the volume maxed and it doesn't change. Everything that I've read on hear and elsewhere looks like I have to return it...is there a fix that I've missed? I'm so sad but without being able to hear it's pretty useless as a phone!
