Help HTC with xbox?

I would like to know if there was any way/shape/or form of allowing the HTC inspire being a storage unit for the xbox. Like, I can plug it up to my xbox and the phone screen will ask me if I want to mount it but it does not appear on my xbox screen. Is there an app or a certain way I can get the xbox storage files onto my phones SD card and be able to save from my xbox to my phone or just simply allow it to appear on my xbox memory unit list? please someone help me ANY way possible.
