Google Talk for mobile

FYI,some of the android phones, they already come with google built-in app. What if you couldn't find one, you may try open straight from your browser at https://talkgadget.google.com/talkgadget/popout

Or you may install fring at http://www.fring.com/ to use the google talk on your mobile.
Ebuddy is also a webservice for google talk but it lacks of security due to the password is not encrypted.

Enjoy..
