My visual voicemail wasn't working so I called Verizon and they said it was never added onto my account...which is a lie considering it worked on day 1 but never again after that, but whatever.
So, I tried reinstalling it and I get the "HTTP Error 400: Bad Request The Server could not understand the page request, or was unable to process it for some reason. Please try loading a different page."
I then deleted the application, and tried to reinstall...same error.
I did a manual reset and I took out the battery and put it back in. Nothing works and I keep getting the same error.
