When I first got my Motorola Droid it had perfect signal strength in my house. 2 months after now it seems I can't get above 2 bars. I am not sure if this is possible but I remember someone telling about some way to call a certain number and then follow a set of instructions that will fix some signal problems. (something like adjusting it to use a closer tower or something). I really don't know much about it. If anyone knows anything about what I am talking please help me.
