My first XNA game for Windows Phone 7 is out the door.  One thing that is nice about XNA is that I was able to leverage a ton of code from my previous Xbox 360 game (Wayne The Brain).  This time around we decided to do a collection of mini-games with online leaderboards.  Taptitude is the name of the collection and Taptitude: Volume 1 contains the first 5 mini games.
