We're not entirely sure what's going on at Nokia HQ, but whoever has populated the specification sheet on the website is probably being heavily spanked as we speak. We recently covered how the specifications for the Nokia Lumia 800 were updated on the official product page to remove TV Out and Mass Storage capabilities.
We now have word, courtesy of 1800PocketPC, that there's another fault in the Lumia 800 specifications. Dolby Digital Plus and Dolby Headphones. The product page has been updated recently to remove these entries, but they can still be viewed on a cached version of the page (alternatively, search for "http://www.nokia.co.uk/gb-en/products/phone/lumia800/specifications/" on Bing, highlight top result and click on "Cached Page"), thanks to Bing. You can find the Dolby audio features under Music & Audio.
So, what's next to go?
