Microsoft and Nokia are currently holding developer events alongside the Windows Phone User Group at Modern Jago in East London. Microsoft has rented it out to provide a central location for all platform exhibitions and events to take place - it's a superb building.
Back in December, at a recent WPUG meetup and AlphaLabs event, those who attended witnessed a row of white Lumia 920 Windows Phones on one side of the main conference hall. These handsets were each running an interesting app, more on this in a minute. Modern Jago has become the place-to-go for developers and designers to collaborate and share ideas.
