Directed Electronics said a new Viper SmartStart for Windows Phone 7 smartphones should be available by the end of the year.
The SmartStart, which can start your car from a smartphone virtually anywhere, is already offered for iPhone, BlackBerry and Android phones.

The app was demonstrated at a Microsoft conference on Wednesday in Anaheim, CA.
Jeff Sandquist Microsoft senior director of developer relations said of the SmartStart, “The app has changed the way smartphone users interact with their vehicles, and Microsoft is very pleased that this innovative app will be available to millions of Windows Phone users.”
Directed said the SmartStart app has received more than a million downloads. It combines with a $199 module plus a remote start system to start your car from the phone.
