I want to use to following scenario: Copy profile from non-hacked XBOX to USB drive, then to JTAG XBOX. Play games, collect gamerscore/achievements and saves. Copy the profile back to the non-hacked XBOX so that my score/achievements are updated online. I want to use the same profile to play games on my JTAG, but also copy to a stock 360 and play online games which I own. Has anyone been doing this? Is this safe (well as far as we know)? On a side note, I've taken a corrupt profile (due to playing on a banned console) and uncorrupted it and played it online after and it seemed fine. Not exactly related but though I'd throw that in there.
