As you recognize that Google Nexus One really out of date, but now its time to get upgrade. Yup Google just announced video chat capabilities in Android 2.3.4 (coming out with Nexus S handset).
As Google said, the video chat feature works with Google Talk and can be used on either Wi-Fi or mobile broadband networks if your phone carrier allows it. Just like the video calling feature in the desktop version of Google Talk, a camera icon appears next to online contacts that can video chat. Tap the camera and the video call begins. Unfortunately, Android devices only support a single account for Google Talk. Need a little change here???
