Google Docs gives you document storage in the cloud, so why shouldn't you be able to access your documents anywhere you are connected to the cloud -- including your iPhone? Well, Google Docs viewing on the iPhone has been a bit kludgy ... until now.
Thanks to MiGhtyDocs (iTunes link), you are now free to roam about the office to view your Docs on the go. You can't edit and you can't view spreadsheets or presentations, but MiGhtyDocs does cache your documents for offline viewing.
This application just does one thing, and does it great. And did I mention that it's free? You can download MiGhtyDocs from the iTunes App Store today.
