If you have an iPhone (or an iPad), here's an application you can use to audition and download sounds directly from your phone, when you're on the go! You can also post forum topics, rate or leave comments on freesound.
It supports all sound formats except .ogg and .flac files. It has a very simple user interface and the sounds that you download, can be shared with your desktop pc or mac via email or fttp.
The app is called 'download manager' and costs $1.99 at the app store. There's also a free version called 'download lite' which limits you to only seven downloads.
here's the direct link to the app in iTunes app store:
