Aha, Google has released a web based version of Google talk which is specially designed for the iPhone and iPod Touch. To get online with the Google Talk, you will need that Safari browser running after you login into the Google talk. If you switch to other application, your session will be disconnected and will reconnect you back when you return. Wanna try? Just put this url on to your iPhone and iPod Touch browser: http://www.google.com/talk.
