AT&T on Friday released the Voicemail Viewer app for iPhone (free, App store) and BlackBrry users, which lets them access their home phone messages with visual voicemail. U-verse Voice subscribers can view their home voicemail messages in a visual list, not unlike an e-mail inbox, allowing them to listen to them in any order as they would for the cellphone's own calls. The app will also notify users when a new voicemail is left on their home phone.
