I have a Motorola Droid, and it has been working great for the month I've had it. Since this morning, I've been getting an error message saying "com.android.phone is not responding" and makes me force close it. As a result of the force close, it shows I have no service momentarily. Because of this, I cannot get calls, texts, and whatnot. I haven't installed any new apps recently, and have already done a "Factory Reset" from the settings. I don't know what to do, please help me!
