If you have ever recorded an outgoing message on your cell phones voicemail, you know that the results aren’t always as desired. The same goes for the iPhone. Having to record your message through a phones built in microphone doesn’t always sound that great. Luckily, iPhone Alley has an iPhone hack that allows you to use any audio file you want as your outgoing message.
On the iPhone, go into voicemail and tap “Greeting”. Record a few seconds of something and tap stop. Before you tap save, use iFuntastic or SFTP to navigate to /var/root/Library/Voicemail on your iPhone. You’ll see a file called “Greeting. amr”. This is the audio you just recorded. Delete that file and replace it with your custom message which should then be renamed to “Greeting.amr”. Tap “Play” on the iPhone to verify your message works. If it plays, tap “Save” and your custom message will be uploaded to AT&T’s servers.
Just follow these few easy steps, and you will have your favorite song greeting greeting people before they leave you a message in no time.
