Disk mode on the iPhone/iPod Touch!
I know the iPhone and the iPod Touch don't have a lot of storage, but it would still be very useful to use them in disk mode. I found out about this great utility called "DiskAid" that makes it possible to use the iPhone/iPod Touch in disk mode. What is even better about this application is that it runs on your Mac and you don't need a jailbroken iPhone/iPod Touch. It is basically compatible with a standard 1.1.1 to 1.1.4 firmware iPhone/iPod. More info and download link here on MacUpdate.
