iOS: Amazon's Cloud Drive is a solid alternative to Dropbox. Android users have had access to the standalone app since late June, and iOS users can now also use it, thanks to Amazon's newly released Cloud Drive for iOS.

Check out the app at the iTunes store, and read the full post at the link below.
