Nokia, T-Mobile and the Dark Knight team up for the Lumia 710 Xpress-on covers promotion

We brought you the news, even before it was official, that T-Mobile and Nokia were teaming up here in the US for Batman the Dark Knight Rises promotion. The promo involves specially crafted Lumia 710 Xpress-on covers in cyan, magenta, yellow, black or white and feature the iconic Batman logo.

Nokia has now officially announced the availability and details of the promotion and we like what we hear:

• The promotion will run exclusively at T-Mobile stores from June 20 – July 31, during which customers can pick up their covers in T-Mobile stores
• TDKR Xpress-On covers are free to existing Nokia Lumia 710 customers, as well as with the purchase of a new Nokia Lumia 710
• Learn more about the exciting 4G Nokia Lumia 710 Windows Phone and the TDKR Xpress-On cover offer here:  www.nokiausa.com/us-en/thedarkknightrises

What's more if you tweet the hashtag #Lumia710NYC starting on June 20th, you'll be eligible to win a ticket  to the US World Premiere of The Dark Knight Rises in NYC on July 16.  But really, how cool is it if you already own a Lumia  710 on T-Mobile you can evidently walk in and pick one of these bad boys up for free? 

Don't have a 710 yet? Now through the end of July and after a $50 mail-in-rebate you can get T-Mo's Lumia device for free on contract. Not a bad deal at all. And besides this T-Mobile offering there is the Dark Knight Rises app from Nokia to complete the movie experience. Read our T-Mobile Nokia Lumia 710 review right here if you're thinking about buying this phone--we rank it rather highly.

So the question we have for you of course is which color are you going to get?
