We ran a story a few days ago showing the Dark Knight Rises logo on the Xpress colored backs for the Lumia 710. We now have an update to that story with the details. T-Mobile will be giving these out for free with a special new promotion starting June 13-July 10th when you sign up on a new two-year contract, either as an upgrade or a new customer.
New customers will get a colored back for free in the store at time of purchase, there is no mail in special for the colored Batman backs. These backs are limited, so be sure to go get them quickly before they run out. The Lumia 710 will also be free with a mail-in-rebate for Classic voice plans. Not only is getting a Batman colored back amazing, but you get the phone for free.
Nokia knows how to sell their devices by giving customers a solid and great experience at a affordable cost. This new cross promotion will sell more 710's, not that they needed any help, and get more windows phones in peoples hands. Although AT&T has the largest variety of Windows Phones, T-Mobile is doing a great job with only 2 that are currently being sold in stores (the Lumia 710 and HTC Radar).
Get your Batman on starting June 13th, the sooner the better. That way you can be one of the few rocking that sweet Windows Phone with a colored back showing off your love for the Dark Knight!
