The European Lumia 900, which was announced at MWC earlier today (or yesterday for those GMT and beyond), is now available for interest registration at the Carphone Warehouse. The Lumia 900 is also going to be stocked at other retailers including Unlocked Mobiles, and sports a 4.3" AMOLED (with ClearBlack technology) display, 16GB storage, 8MP camera (with FF), 512MB RAM and a 1.4Ghz chip.
No word on the pricing as of yet, but we suspect it'll be competitive and will look to be around the £450 mark. According to the registration page, they are looking at a June 2012 launch.
