Dialing under the influence got you sleeping on the couch again, in your car? Save you, from yourself, with iBlackout: Save me from myself. Set up a blacklist of contacts and a time limit for your time out. During the blackout period you will not be able to text, iMessage, facetime or call the contacts on your blacklist. Hopefully this will save you from some of those embarrassing apologies in the morning!
Settings are available in both settings and an individual application.
