T-Pain and Smule are now bringing Auto-Tune to the Apple iPhone which is basically an easy way to simulate what karaoke would sound like screamed over a really bad mobile phone connection say theiphoneblog.

Apparently once you have recorded your songs with Auto-Tune for iPhone using the built-in tunes of your own freestyle songs you can share them on MySpace and Facebook, and additional tracks are available for purchase.

We have a video for your viewing pleasure of I am T-Pain Auto-Tune for the iPhone which lasts almost 3 minutes and can be viewed below so hit it up and enjoy.
