According to engadget mobile http://www.engadgetmobile.com/2008/07/02/google-crafts-web-based-google-talk-for-iphone/#thankYou google talk is coming for iphone. It is a very important news for me, because I am thinking between ordering 200 txt per month ($5) and 1500 txt per month ($15) with my Iphone 3G when I get it. Most my friends have gmail, my wife has google talk on her blackberry so it will dramatically reduce my txt message use if it is true. To save $10 a month is big. Because of nature of my work I text more than I call (work in environment when calling is disruptive). But again I am wondering how it will work.
