When I tried to place a call this morning (shortly after pulling it off the charger), I got a high pitched squealing noise coming through the ear piece. When I connected to the person on the other line, the squealing continued and they couldn't hear me. I rebooted and the noise went away. I haven't experienced it since. Any ideas as to why this occurred? This happened to a few others over on the Verizon forum and they suggested *228 (option 2) to update the cell towers in my area. I just want to make sure I don't have a defective Incredible. Thanks.
