Until Google Talk releases a mobile version (or anything else), there's a simple way to chat with your friends from the mobile phone. eBuddy, an all-in-one web messenger similar to meebo, has recently started to support Google Talk. eBuddy has a mobile version available at m.ebuddy.com that can be used to chat with your contacts from Yahoo, MSN, AOL, Google and MySpace.
The interface is very simple, but it's optimized for the small mobile screens by displaying the messages in the reverse order. The web page refreshes every 20 seconds to automatically display the new messages.
While eBuddy promises it doesn't store your usernames and passwords, you should only use the service if you think it's trustworthy. There are many other ways to access Google Talk on your mobile phone, but this one doesn't require to install an application. iPhone users should rejoice.
