I've had my X since Sept 2010 but over the past 48 hours or so I have been unable to make or receive phone calls. I can dial out but I hear nothing even though it shows that my call is connected-the person on the other end cannot hear me but their phone does ring and they answer but then there's nothing. My phone will ring when someone calls but when I answer it again there is nothing there for me or the caller. I can text, play games, surf the internet ect... basically everything is working fine except the ability to actually use the X as a phone......any thoughts out there before I have to go hang out in the Verizon store for a few hours to get it figured out? Thanks in advance for your thoughts.
