If you are a user of Google Talk program then you can now access this one via your iPhone Safari browser as well. It would further work with the iPod Touch. There are some slight differences when contrasted with the desktop version, or else Google kept it as same as possible.

Google's Official Mobile Blog stated "We've just released in the US a new version of Google Talk designed specifically for the iPhone and iPod Touch browsers. In addition to sending your friends Gmail messages from your iPhone, you can now chat with them while you're on the move, too! In your iPhone browser, just go to www.google.com/talk, sign in and start chatting. That's it. Google Talk runs entirely in the browser so there's no need to download or install anything.

There are some differences from using Google Talk on your computer. For instance, in order to receive instant messages with Google Talk on your iPhone, the application needs to be open in your Safari browser. When you navigate away to another browser window or application, your status will be changed to "unavailable" and your Google Talk session will be restarted when you return."
