Google announced an improvement to the mobile version of Google Docs. That is list view for spreadsheets, which allows you to view, edit, sort, and filter your spreadsheets from your mobile device.
Previously, you could only view your spreadsheets on mobile devices. Now, they basically have full functionality.
The mobile access even made better by adding new capabilities with List View for spreadsheets. You can quickly view, edit, sort, and filter your spreadsheets on a variety of mobile devices including Android-powered devices like the T-Mobile G1, the iPhone and iPod touch, and the Nokia S60.
