AT&T has quietly begun selling the iPhone 3G through its website. The move to offer the handset online is the first time it’s been available online in the United States, although it is sold online in other regions such as Hong Kong and Italy where the handset is available unlocked. Like with online sales of the first-generation iPhone, iPhone 3G units purchased online will need to go through an in-home activation process before use. The online ordering process includes credit and number portability checks for new customers, similar to pre-purchase screening tools launched by Apple and AT&T earlier this year. In addition, customers can choose to speak with an AT&T representative via online chat. AT&T shows eight days remaining for customers to order in time to receive their iPhone 3Gs by Christmas, and is offering free overnight shipping with each order. Apple has yet to begin offering the iPhone 3G online through its own store.
