If there was any doubt as to which iPhone 4 feature Apple feels is the device's strongest selling point, then these new commercials certainly clear things up. Apple recently rolled out four new iPhone commercials which all focus entirely on Facetime, and in typical Apple fashion, all strike an emotional chord.

First up is an ad called "Smile", featuring a teenage daughter who's a little embarrassed to show her dad her new braces.

Next up is "Meet Her" which shows a video conversation between a new father and his own dad, a grandfather for the first time.

And below is "Big News", which shows a wife telling her husband that they're finally going to have a baby.

And last but not least is "Haircut", featuring a girlfriend showing off her new haircut to her boyfriend.
