Existing AT&T customers who want to jump onto the Lumia 920 ship can purchase the smartphone for $69.99. The price is valid for both individual and family plans and for current customers who want to either upgrade their current smartphone or add a new line of service.

The "Without a Service Plan" price is $449.99.

The offers for both new and current customers are still lower compared to AT&T Online. The official AT&T website is offering the Lumia 920 in cyan, white, and yellow for $99.99 when signing a two-year contract. The black and red Lumia 920 smartphones are currently out of stock.
