A New Google Talk for iPhone that uses the iPhone browser has been released. Since it runs on your browser, there is nothing to download or install. So if you want to chat on the go, just point your iPhone browser at http://www.google.com/talk. This works both on new 3G iPhone and the first generation iPhone. So stay connected to your Google Talk contacts right from your iPhone.
If you are a Google Apps user, you can use your Google Apps account to IM over iPhone's browser, just visit http://talkgadget.google.com/a/whatever.com/talkgadget/m, but be sure to replace 'whatever.com' with your domain name and you will be able to
- Chat with contacts in real time
- View and search for your Google Talk contacts
- Update your status message on the go
