If you have an iPhone with a MobileMe account, the MobileMe iDisk is a free app that gives you access to all your iDisk files on your iPhone or iPod touch. You can view many files types including Office (Word, Excel) iWork (Pages, Numbers), PDF, Images, Movies and more. After you choose to view a file, it is downloaded to your iPhone or iPod touch. You can view the files in landscape by rotating your device. Pinch and swipe to navigate file contents. There is a Recent tab that shows files you’ve already download, which avoids having to do so again.

iDisk also makes sharing files a breeze from your iPhone or iPod touch. Tap the share icon for any file to email a link to the file to a friend. You can optionally set a password and the length of time the link will be valid before it expires. Your Shared files tab lists all the files you’ve shared previously and from there you can un-share files very easily as well.
