Sometimes we wish for an undo in the iPhone’s Phone app, mostly when we accidentally delete a voicemail message. You might just be in luck. Next time you you accidentally delete a voicemail message, try this:

• Open the Voicemail screen in the Phone app.
• At the bottom of the screen, select Deleted Messages.
• Select the message you wish to restore and then click Undelete.

Unfortunately, this won’t help you get back those voicemails you left on other’s phones at 2 in the morning.
