I have seen a number of applications that allow read and write access to iPhone so it can be used as a portable drive.

I am looking for an application that would allow me to play music (read access) from the iPhone on multiple PC computers and write music to the iPhone library. I have seen iPhone drive for the Mac that does all of this. Is there anything like this for PC? I was thinking of setting up SMB for the iPhone, but that does help decrypt the iphone music library.

Any help on this would be apprciated.
