Microsoft has just sent out the official invites to a Windows Phone 7 press conference. On Monday, October 11th, Ballmer will take the stage in London and give us all some new details, demos, and likely some actual device announcements. Unfortunately, you may have noticed I said the conference was on a Monday. For the OTN crew anyway, Monday is a school day and that means no live-blog. Sorry. However, any and all of the information released there will be posted right here soon after. The conference starts at 2PM (6:30 PST) in London and will run until 5:30.
