Mac and Palm software company ecamm has recently released iPhoneDrive, an application that transforms your iPhone or iPod Touch into an external storage device. Now people can access the capacious sufficient tiny leftover space on their iPhone’s memory to store files that don’t currently work with the iPhone’s current software. So while it certainly makes sense to use audio and video files, for example, from within the iPhone’s own iTunes framework — perhaps using Apple’s handy video-out cables to show them to your class (see story), you might also want to bring those documents for editing or those backup files with you by treating your iPhone or Touch as a handy flash drive.

While the software doesn’t allow the iPhone to access the files it’s carrying as iPhoneDrive data, the application does offer some nifty advantages, and we could see it making teacher’s lives a little bit easier as they shlep their files from class to class. A free demo version is available here.
