ReaddleDocs Forum Review by msbaylor. (Visit the thread for video and more pics. For more Forum Reviews, see the TiPb iPhone App Store Forum!)
ReaddleDocs is a document viewer that basically covers all the ways of getting the document onto you iPhone – so there is no way that you cannot have your documents on hand.
When you purchase ReaddleDocs, you also receive 512MB of storage space on their server. This allows you to upload any documents to the server via any browser and then sync them with you iPhone via any data connection (EDGE/3G/WIFI).
When you tap on the “Online” tab, you select the server you want to connect to and then you have the ability to sync with the server so that any new documents that you have retrieved via the iPhone will backup to your server and vice versa.
Besides using your Readdle Storage space, you can also connect to your MobileMe iDisk or connect to a WebDAV enabled server.
