Back in January, Datviz updated the Documets To Go to version 3.0, making it the only mobile Office application for the iPhone to support the viewing and editing of all three Office formats (Word, Excel and PowerPoint). It has now added support for Google Docs with the release of Documents to Go Premium 3.1.

According to the developer, access to the Cloud has become more and more important to its customers. So, with Document's 3.1, it is starting off support for these types of remote services, with Google Docs access.

As a result, the mobile office suite now lets:

o Download, view & edit your files from Google Docs directly in DocsToGo
o Save and synchronize changes back to Google Docs
o Upload files to Google Docs from your iPhone or iPod touch
 Access multiple Exchange and Gmail accounts
 Freeze rows or columns in spreadsheets

Documents To Go Premium goes for $14.99 here. All those who purchased a previous version will receive a free update to version 3.0.

In addition, DataViz has submitted an update (also version 3.1) for its base "Documents To Go" product ($9.99, available here). At this time, it is "In Review" and once approved, all those who purchased a previous version of "Documents To Go" will receive it for free.

This update adds:

o Support for Gmail attachments
o Editing/viewing attachments using Docs To Go
o Freezing rows or columns in spreadsheets
o An In-App purchase option to upgrade to the Premium version
