Apple has launched an aggressive ad campaign to maintain the strong sales momentum of the iPhone 3G. Three new TV spots have been posted on Apple's website with the theme "What is a 3G." Two of the ads focus on the iPhone's improved speed, the third touts the iPhone as a work tool. The spots are already running on television and specific versions have been produced for other countries.

The commercials are simple, with a hand holding an iPhone as it is demonstrated.The basic message of the first ad "Everyone," is that users can surf the Internet at twice the speed, for half the price.

The second spot,"Unslow" defines "3G" as fast, easy internet access.

The third spot Work Friendly" shows an iPhone 3G downloading e-mail and syncing calendars, and shows Apple's eagerness to grow in the enterprise market.
