If you ever use the gps, try turning your music on. Test that it will always drop the gps signal with music on. Then e-mail and call HTC like crazy about this issue until they either replace our phones or if it's a software issue then release a patch.
EDIT: Since most people started flaming me, I will post more information to validate this error. It seems to be external speaker related, as far as I can tell using headphones will not cause any problems.
