Google has made available a mobile version of Google Docs application, which can be downloaded from docs.google.com/m .
The interface includes “Recent Documents” inlay at the top and “Your Documents” at the bottom, as well as a "Search Docs" bar. The program is supported on the iPhone, BlackBerry, and on any other handset with rich Internet capabilities. Depending on your phone different functions will be available to you.
The main downside of the Google Docs is that it can not edit documents.
