T-Pain and his media team (along with Smule) have put together what I believe is the most fabulous advertisement for any iPhone app I’ve ever seen.

The app which is called “I Am T-Pain” basically turns your regular iPhone into a portable auto-tune machine. For $2.99, you can record your own voice with the same auto-tune effect that T-Pain uses and then email, Facebook, or Myspace the track once you’re done recording. The app also does on-the-fly auto-tune, so you can just speak into it and hear your voice with the effect on it right away.

Anyway, just look at the amount of celebrities T-Pain managed to get in this one video touting his iPhone app. It’s insane. And that last portion with Akon…haha, that’s just hilarious!
