Apple Thoughts: Spreadsheet Editing on the iPhone Available in Google Docs

"A while back we noted that Google had optimized the Google Docs services for viewing on the iPhone (and other mobile devices). It's taken a while, but now it's been announced that some basic editing is possible from the iPhone as well."

This may come in handy on the fly when you get some updated info and need to adjust the spreadsheet, but from what I've read, it isn't the easiest way to make changes. It is still best done on either your desktop or laptop, but at least this is a good start towards mobile functionality.
