Nokia Lumia 820

4:30pm: A final post press conference note: in a Q&A after the announcment, Elop said Lumia 920 and Lumia 820 would enter the market in the final quarter of 2012, but would not announce pricing. When asked about a Lumia tablet, he said: "With Nokia's strength in mobility this is an area that we are evaluating very closely. It's a real opportunity." Interesting.

4:25pm: And that's all folks. Thanks for joining us and make sure to check out our indepth coverage of the Nokia event in the coming hours, days and weeks.

4:23pm: Ballmer gone and Elop back up for what is likely the wrap up. Talking about how far Nokia has come with Windows Phone.

4:21pm: Ballmer says in the next year we will see 400 million new Windows devices (phones, tablets, laptops and PCs) which should attract app developers.

4:20pm: I think that Steve Ballmer has been telling Stephen Elop to go to the same suit supplier as him - and that's not a good thing

4:17pm: Ballmer has been asked by Elop to talk about the ecosystem as a whole and is onto Windows 8.

4:15pm: Microsoft CEO, Steve Ballmer now on stage with Elop. Says its been a "full on sprint" to get Lumia to market but we're only now seeing the results. Oh and he's talking about live tiles again. Jeez....

4:13pm: We're onto the Lumia 820, which comes with a number of exchangeable covers - one of which adds wireless charging. Very similar to 920 but with no PureView and smaller 4in screen but keeps super sensitive technology.

4:10pm: While Nokia is esposing the benefits of its new phones, the markets seem to not believe them. Nokia stock on the New York Stock Exchange is down over 13 percent since opening this morning.

3:51pm: Kevin talking about the engineering side of Lumia 920, like the inclusion of the polycabornate shell, first seen on the N9, which allows Nokia to offer the phone in yellow, red and slate grey colours - giving the phone "personality, style and a little bit of panache." Nice.

3:50pm: Oh good, Kevin Shields is on stage, let's hope he does this again.
