Did your earpiece go silent in your Droid Incredible?

About a month ago when answering a call with my Verizon HTC Droid Incredible I realized that I could not hear the person. I switched on speakerphone and was able to hear them just fine. If I switched off speakerphone, everything went silent on my end. This carried on for about a week and I got fed up with it. I did some searching on the Internet and found that there seems to be a variety of Android phone users who have had this problem sometime after their phones were updated to Android 2.2 from 2.1. I called HTC. They were useless. Of course it was a weekend and I would have to call back during normal business hours, bla, bla, bla. I popped off the battery and left it unpowered like that overnight. The next day it started working again. It's been fine for a few weeks now. I just wanted to put this out there so someone with this problem might find it and try this tip.
