Three new iPhone 4S advertisements have been launched by Apple.The ads highlight the features that keep iPhone 4S ahead of iPhone 4 – iCloud, upgraded camera and Siri.

The ad on the camera highlights the device’s photo editing capabilities, beside projecting its Twitter integration.

The ad on the iCloud informs the viewer that if he downloads a song on his iPhone from iTunes, then the song will automatically show up on the iTunes of the user’s Mac. The ad also shows that if the user bookmarks a page while reading a book in iBooks, then the same mark will be in sync with his iPad.

The ad on the Siri shows how it uses the phone’s map application to give necessary direction to the user who is to visit a certain hotel. The ad also shows how a child helps the service to have some idea about how the weather will be on that day.
