I just turned on my iPhone to check for updated applications after reading that Navigon was updated with some very cool new features and discovered that Quickoffice Connect Mobile Suite version 3.0 (iTunes link) just became available today. Here is the full press release for this latest update. This new version of Quickoffice has come a long ways since my earlier review and now lets you access documents through Google Docs, Box.net, Dropbox, and MobileMe accounts while also providing general product enhancements. Without file system access it has always been a challenge for developers of these types of apps to help you access your documents and this looks like a great way to provide that support.
To start with you need to create a Quickoffice account or sign into an existing account. You then simply select a service to add, enter your credentials for that service, and then will see that service folder in your list of documents to edit or view, along with email attachments and locally stored files. I am particularly happy with the Google Documents support and may start using this mechanism for document storage and access even more now. I also see that this suite is available now for just $9.99 and provides you with Word and Excel creation and editing capabilities with PowerPoint support coming this year too.
