I mentioned Soonr almost two years ago. It is a cool application that lets you access files on your computer from your phone. Soonr just added support for the iPhone, so you can sync up to 500MB of files to your iPhone, print to networked printers, and more.
If you need occasional access to your files, but don’t want to lug along a laptop, Soonr still looks like a pretty great little app.
