I love everything about this phone, except the fact that the earpiece volume cuts out at least twice a day. The problem is that I will be on a call, and all of a sudden I will not be able to hear the other person. The call will stay connected and the other person can hear me just fine, but I can't hear anything. If I end the call, turn the phone off and turn it back on and recall the person it will work fine. What's wrong with my phone and how can I fix it? Its an unlocked phone and I'm using it with Cingular.
