So the rumours were correct, right down to the name. Yes, the Nokia Lumia 800 has been confirmed as the flagship Nokia Windows Phone 7.5 handset at the start of the Nokia World event in London.In fact, this phone has been talked about for weeks, originally with the codename Sea Ray. Don't know about you, but I think I prefer that. But forget that branding and get used to Lumia, which is the 'catch all' name for the initial crop of phones produced in conjunction with Microsoft.Yes, it's not alone in launching today as a Windows Phone, but the Nokia Lumia 800 is the headline act. Described as 'stunningly social' and with a 'head-turning design' by Nokia, the Lumia 800 comes in the bold colours of cyan and magenta (plus...erm...black), packing a 3.7-inch AMOLED ClearBlack curved display in that sleek and slim body, along with a 1.4GHz processor with hardware acceleration and graphics processor, an eight-megapixel 'instant-share' camera with Carl Zeiss optics and HD video playback (along with 720p HD capture).Of course, you get the Windows Phone 7.5 (Mango) operating system keeping everything ticking along, 16GB of internal user memory and 25GB of free SkyDrive storage for storing images and music in the 'cloud'. Dig deeper and you'll also find one-touch social network access, threaded communication, optimised navigation by the name of Nokia Drive (free, turn-by-turn navigation in essence) and for you music lovers, MixRadio, described as a free, global, mobile music streaming application that offers hundreds of channels of locally-relevant music. Later in the year, an update will allow you to create your own music channels via MixRadio too. If that's free, it could be a neat alternative to Spotify.Fancy owning a Nokia Lumia 800? It's now available to pre-order SIM-free via Nokia, with a shelf date of November. So not long to wait. The SIM-free price is €420.
