Hey there! I have had my Hero for about a week (first Droid!). I am no longer getting sound or vibrate text or email notifications. I don't really care about the email notifications, but I need the sound and vibrate for texts! I have checked the forums and found several threads where downloading Sound Manager resolved the issue. It didn't work for me. I have also checked Settings> Sound & Display > Notification Sound. There is a tone selected. I tried a battery pull as well. Any advice anyone can offer would be greatly appreciated!
