Box.net Upgrades IPhone App, Announces New API

"Box.net provides cloud-based file-sharing and collaboration tools aimed at business users. A variety of iPhone apps already integrate with the service.

Of course, Box.net offers an iPhone app of its own as well, and on Monday the company announced that the app has been upgraded with oodles of new features. In addition to the app's core functionality--which lets you view and share your files--the new version incorporates the ability to comment upon the documents and folders you're sharing. That way, you can exchange notes with your colleagues on important documents, from anywhere."
