People can't hear me on my iphone?
It's not an iPhone issue because I replaced it 3 times and currently I have an iPhone 5. The person calling or when I call someone start hearing me and then it starts to break. Sometimes I change ears and it comes back and then breaks again. It's frustrating. People from Apple told me to restart the iphone many times and to set it up as "new phone" as it could be something wrong when I copy stuff from iCloud.
Please any ideas are welcome! I really don't want to go back to apple store.
Thanks in advance!
