DiskAid

With DiskAid you can access the file system of the iPhone and the iPod touch without the need of a Jailbreak. Thus, the iPhone and the iPod touch can be used as a mobile storage solution.

Also you also get access to the stored music, video and image files.
Note:
Since version 3.1 DiskAid is no longer freeware. We therefore offer the last free version 3.0 for download. The latest version is available on the website link.
