Want to see Katy Perry in concert for free? Make your way to AT&T stores in NYC to snag tickets to tomorrow night's performance, in celebration of the launch of the new Windows Phone 7. Tickets are on a first come, first served basis. Line up to get your tickets at these participating stores tomorrow, November 8th.

If you're not in NYC, you can pick up tickets for a west coast celebratory performance with Maroon 5 in San Francisco tomorrow at these participating stores.

I'll be picking up my own new Windows 7 phone tomorrow. I'm looking forward to seeing all the fun new features, including Live Tiles, Xbox Live integration, the People, Office, Music and Video hub and more.
