Ever wanted to save or share a voicemail? On the iPhone, every voicemail message is just an audio file. If you want to retain a message for posterity or share one with a friend or colleague, you can do that easily. While viewing a voicemail message, tap the share icon (the box with the up arrow) to bring up an activity sheet. In it, you can save the file to any app that can handle audio files, or share the file with AirDrop, Messages, Mail, or the like.
