I have a droid 2 and I have had it since December of 2010. Just here recently, I have noticed that I haven't been getting all of my calls. People say that it rings but my phone itself doesn't ring. This has just started within the last few days. I have tried shutting my phone off and turning it back on but my calls still don't come through. I am starting to get frustrated with it because people are getting mad at me because they think I'm ignoring them... Help with this problem would be appreciated 
Thanks
Aaron
