While the launch date has shifted several times over the past two months, BGR reported in January that the Lumia 900 would become available from AT&T at a shocking $99.99 price point — the lowest launch price for a flagship phone in recent history. The handset’s release will be accompanied by a marketing and advertising blitz aiming to familiarize the U.S. with Windows Phone, but educating the sales staff at AT&T stores and encouraging them to pitch the handset is a crucial piece of the puzzle that could lead to the device’s success. Nokia is reportedly taking things one step further — wpcentral on Friday reports that Nokia will finance a program allowing AT&T sales staff to trade in their current handsets for a brand new Lumia 900 at no cost. The program, which will see AT&T employees turn in iPhones and Android handsets for the Lumia 900, will reportedly cost Nokia as much as $25 million. BGR took a hands-on look at the AT&T’s upcoming flagship Windows Phone during the annual Consumer Electronics Show, and we described it as a gorgeous handset that improves upon the already-great Lumia 800.
