Quietly and without warning, Google has launched a full-fledged iPhone version of all the core Google services rolled up into one easy to use menu. This new iPhone menu includes all the great Google apps we know so well (Search, Gmail, Calendar, Reader, Docs, SMS, Goog-411, News, Photos, Blogger, and Notebook). This new interface has that familiar iPhone UI which has already been adopted by many other sites such as Facebook.
The screens are simple, intuitive, responsive, and work well for multi-touch interaction. To access Google for iPhone, simply go to Google.com which will recognize your device and serve up the optimized version of the site automatically.
