For those iPhone users with a MobileMe account, Apple has released a free application called iDisk. This utility allows iPhone users running iPhone OS 3.0 and later to view and share the contents of their MobileMe iDisk on the go.
iPhone supported file types are viewable in landscape or portrait, and can be zoomed in using standard pinch gestures. Using the Share button, MobileMe subscribers can send emails with links to large files without even downloading the file. Public folders are also accessible using the iDisk application.
