Hi everyone, I just got the Moment and I like it so far, but for the love of God I can't figure out how to turn the sound off when my phone goes out of service. Where can I find this!? I live in an area with poor cell service (I knew this and I hate talking on my phone) and just want the noise shut off. I don't need a stupid beep to tell me that it's outta service. It's driving me nuts. Please help!! Thanks in advance.
