DiskAid is a freeware utility that allows you to use your iPhone (or iPod touch) as a portable hard drive. All you do is install the program (it’s available for both Windows and Mac), then connect your device. DiskAid automatically detects it and provides a familiar tree-like interface for creating folders, copying files, and so on. Best of all, you don’t have to “jailbreak” your unit in order to use the program.
