I got one of these recently, virgin mobile and Target, and I like the phone but the microphone doesn't seem to work. I tried it with headphones and it works fine but using speakerphone or regular mode nobody can hear me. I can here them fine but I put out absolute silence. I think I'm within my return period but if anyone knows how to fix this issue I'd appreciate it. I've tried hard resets,etc, but no dice. I've found no information anywhere about people having a similar issue. Thanks for any help you can give.
