With Mango just around the corner, hopefully we’ll see WP7 start to make a dent in the smartphone market. One of the things missing from the current OS is Google Talk or GTalk. Well, thanks to Luis Hector Chavez, an app called GChat is now available in the Windows Phone Marketplace. This free app will send push notifications onto your live tile and even “pin” a GTalk contact to get to the conversation quicker. Go and check out this app and let us know (let Rad know) what you think!
