So you've got the cosplay Batman outfit, the turbine-powered Batmobile and are in the closing stages of finalising planning permission for your Batcave, but no aspiring Batman is complete without all the latest gadgets. So it's just as well you can pop to your local Phones4U and pick up an official Batman mobile phone.
The Batman symbol touting Nokia Lumia 900s will be available from select Phones4U stores from 1st June and for pre-order on the company's website from 29th May. You'd better be quick, though, as only 900 of the devices will be sold.
Although arguably not the most gadget packed handset, the Lumia 900 does make for a good Batman match thanks to its splendid matt black plastic chassis. Otherwise its single-core processor, 4.3in AMOLED screen and 8megpixel camera combine to make a competent if not entirely exciting handset.
As well as the phone you'll also get two free tickets to see The Dark knight Rises, as will anyone that buys a Lumia 900 from Phones4U, Batman or not. There's also a Dark Knight Rises app that is exclusive to Nokia taht includes trailers, wallpapers ringtones and a location-based challenge to "Claim Gotham City" by checking in using Foursquare.
