GChat was developed for Windows Phone Mango. Just like the standard text messaging feature, the GChat application will send push notifications to your handset. You can take any of your contacts from GChat and pin them in a tile of their own directly on the home screen. You can also have what is called off-the-record conversations that have special and delicate handling.
The GChat application is available for download now in the Windows Phone Marketplace and can be had for the appealing price of free. Check out the GChat app and tell us what you think in the comments below.
