Along with the mobile-browser option, Google Inc. is adding support for retrieving driving directions through text messaging. Last year, Google began offering a host of mobile search services using SMS (Short Message Service).
I have been using GOOGL or 46645 then a zip code and name of restaurant to find restaurant listings when I am out and about. It only works with 46645 on palm treo phones I have noticed because of the keyboard layout. Itís a wonderful & HANDY service that I do not see anyone else besides google doing yet.
