aDownloader is a download manager that lets you download many different files to your iPhone or iPod Touch. With over 40 supported files, aDownloader will download all your files over any available network, from any site, including hosting sites such as RapidShare and MegaUpload.
The supported files include but are not limited to:
With aDownloader, you can easily manage and organize your downloads by creating folders, copying, deleting and moving files around.
This app gives you access to multiple simultaneous downloads, with no file limit. You can pause/resume interrupted downloads. If your internet connection fails, you can even resume your download later.
Finally, the best feature seems to be that you can download/upload your files to/from your desktop computer via your web browser.
I haven’t tried aDownloader myself but it sure looks like a winner for those of you who need to regularly download files to your iPhone.
