When I get a voice mail, there is no notification but the icon for the app does show the number of voice mails. when I launch the app I get a message "unable to verify subscription status. please try again later' It has been like this since I got the phoe, so the 'later' part is just fiction. when I press the MENU area to the left of the big HOME screen button, it makes a sound but no menu comes up. What to do?
