For all its pleasures, alcohol can be an embarrassing mix with cell phones -- particularly cell phones with built-in address books with long lists of everybody you know or ever knew, including exes. The Don't Dial app is here to prevent you from calling former loved ones and giving them a piece of your mind while you're under the influence -- of alcohol, or just a maudlin inability to let go. You can block yourself from dialing numbers of your choosing for a 24 hour period, or give a friend the duty of being "designated dialer" by having them set a password. Available for the iPhone or Android.
What's the most useless, crazy, I-wouldn't-buy-that-if-it-was-free app you've seen? Tell me about it in the comments.
