Since the iPhone came out, there has been no office suite app for the iPhone. We have different spreadsheet editors and word processors but nothing as unifying as DTG. Perhaps one of the main reason is the lack of copy-and-paste function. And yes, DTG for the iPhone will have copy-and-paste.
Just last week, Google enabled spreadsheet editing for Google Docs for Webkit browsers. So, for iPhone mobile warriors who need (want) to work on the go, the time is near.

You can sign in for notification here. There's no word if this is for the beta or when it's finally in the app store.
Note: You can bet this app won't be $0.99.
