Use a iPhone/ipod Touch as a network disk

The software Air Sharing available via the AppStore makes it possible to transform a iPhone/iPod Touch into a network disk.
Once the application is installed and launched (and only while it is launched), it is possible to mount the iPhone as a network disk or directly in Safari and to be able to deposit files or to recover them in all simplicity.
The software is free for the moment. However It will, at a unspecified future date, cost $6,99.
