A new Mac OS X application launched in the US allows iPhone users to move files back and forth between their Mac and iPhone. Ecamm Networks' iPhoneDrive costs $9.95 (£5) and a free demo is available for download.

The iPhone already synchronises content, including contact and calendar information, music and video, with the Mac, but unlike the iPod, it can't be mounted as a mass storage device for you to put files on it. iPhoneDrive overcomes that limitation.

The software lets you drag and drop individual files to be copied onto the iPhone. You can also use the iPhoneDrive toolbar to facilitate data transfers, or copy over entire folders.

System requirements call for Mac OS X v10.4.10 or later, iTunes 7.3 or later, a Mac equipped with USB 2.0, and, of course, an iPhone.
