Google launched <A HREF="http://news.zdnet.com/2100-1035_22-6131734.html?tag=nl.e589">a version of Gmail for mobile devices</A> that lets US users do in two clicks what previously took them ten or more. Gmail for Mobile Devices is a free, downloadable Java application. It will work on the nearly 300 types of Java mobile phones in the United States, said Tony Hsieh, product manager for Google Mobile. The software improves on a version of Gmail released nearly a year ago that lets people access their email through a mobile Web browser.
