Flory is a Google Talk IM client for Windows Phone 7. The software uniquely uses push notifications to send notifications when an incoming message is sent, meaning the user can receive messages even when the client is not running. It also features a live tile showing the number of missed messages.
The software is currently exclusive to the German marketplace, but the developer is hard at work translating the app, and should release it in USA soon.
