Since late last year, Windows Phone 7 has captured the minds of many users, both for its attractive looks and deep integration with Microsoft’s services. Yet, many might still be using services outside Microsoft’s umbrella, such as Google Talk. If you’ve been struggling for a way to use Google’s instant messaging service on your new Windows Phone 7.5 Mango device, Gchat is the perfect app for you.

Google recently introduced video and voice chat on their Google Talk app for Android. While, officially, this is specific to Android 2.3.4 only, we’ve gained information regarding how you can video/voice chat using Google Talk on phones which aren’t on Android 2.3.4. Follow the guide after the break!

We first heard yesterday about the possibility of Google’s Android 2.3.4 bringing video calling to the Nexus S, thanks to a tweet from a supposed Samsung employee. Now Google has confirmed that this is indeed the case, and the update will arrive in the ‘next few weeks’.

With Google I/O on the horizon, the Android world was quietly hoping for more than a new release of Gingerbread to be shown, and if one particular tweet is to be believed, we could be in for some native video calling goodness coming to the platform.
