You'll need a different hack to put music or video files from a random computer onto your device too. That's assuming it's even possible, they seem to be in an arms race each new devices having your data further encrypted in some way.
I've got around this in the past by importing the bizarrely named files into iTunes and then telling it to automatically organise my library for me. It then uses the metadata in the mp3s to rename the files back to how they should be. Not sure if it still does that these days.
You don't have to use iTunes, or even an Apple app, to get things on and off an iDevice. For example: http://ecamm.com/mac/phoneview/
