iPhone Can I copy files from PC to iPhone

Probably a rookie question, sorry.

I have an Android device from my employer and one of the few things I like about it is the ability to plug into my PC and copy files to/from the device using Windows Explorer. Looks just like a drive and I have access to the various folders.
My iPhone 4 is jail broken. What do I need to install and do to make my iPhone work the same way as the droid device? Is it possible?
I have ifile installed and an app called phone drive but neither of those work the way I want. That could be due to user limitations as I will be the first to admit I'm borderline moron regarding all things iOS.

Thanks

Thanks for the tip on i-funbox. Not quite what I wanted, but better than what I had. Still wish I could just plug into any windows machine and use windows explorer without needing iTunes and ifunbox.

Thanks BFizzle. That's what I was looking for.
