We know Nokia and director Christopher Nolan have a thing going--after all, Nokia has appeared in a previous "Batman" film and we've seen a limited run of Batman themed Lumia 800's back in December. There were only 40 of those created.
Now they're looking to jump on the release of "the Dark Night Rises" with a more widely available (but still super limited) Batman edition of the Lumia 900, etched with a Batman logo on the back.
Phones4U are confirmed to be getting a batch and the device will go on sales in France and Germany too.
No word on pricing or just how many will be available but it sounds like you'll need to be quick to get one. Also no confirmation of an AT&T version--we'll be surprised if the massive carrier doesn't offer something similar, so we'll keep an ear out.
