Anyone had, or heard of, this issue w/ the MoPho? On several occasions now I've gone to call someone or answered a call, only to realize I cannot hear anything at all through the headset. No static/white noise, nothing, and the person on the other line hears nothing either. In each case I've had to reboot the phone in order to get it to work again. Really annoying having to wait that long just to make a quick phone call. This is really disappointing...I wanted to love this phone, and have been a loyal Motorola user for years, but this issue combined w/ the "sleep of death" has made this phone too much of a hassle in the short time I've owned it. Never thought I'd say this, but I'm looking forward to trading this in for the SG II here shortly.
