I have to know if other people are having this problem. I am getting complaints that nobody can hear me on my new iPhone 5. Seems to be worse when I am in my car or anywhere with background noise. I took it to the apple store today and they gave me a new phone and this one has the same problem. I am going crazy. So frustrating. I never had this problem with my old iPhones. People on the other end say I sound muffled or like I am holding the phone really far away. Anyone else having this issue?
