We recently announced the Windows Phone Inner Circle tour with stops all over the US this fall.  Be sure to put Wednesday, November 2, 2011 on your calendar if you're in San Francisco.  The event will be from 6 - 9 PM, but as of today I'm unsure of the venue.  I'll update this blog as soon as I confirm the location.  (Update: As William mentions in the comments, the venue is at 540 Howard Street in San Francisco.)  The San Francisco event coincides with the HTC Radar 4G launch party.

From the registration page:

"Enjoy free appetizers and cocktails, be one of the first people to get your hands on incredible new Windows Phones, and meet the team that brought them to life.  Share your experience and you'll be entered to win a Windows Phone and other great prizes."    

The word on the street is that lots of phones will be given away.  Be sure to register!  See you there.

Also, be sure you've downloaded the "Mango" SDK here: http://bit.ly/wpgetstarted.  The download couldn't be easier.
