A free-ware application called Simplify Media streams music from any shared iTunes library over the internet, effectively giving your limited-space iPhone or iPod touch access to your entire music library—no matter what the size.

To use it, you’ll need to install Simplify Media on your Windows or Mac desktop. Then, using a jailbroken iPhone, install the Simplify Media app for the iPhone from Installer.app. You’re limited to using Simplify Media to a Wi-Fi connection, and it’s a bit buggy in the beta version, but as you can see from the video, it’s got tons of potential.

Below is a video of this application doing what it does best:
