WM5torage is an excellent app. I used it on a PPC for a while. Just tried it on the Q and it worked fine. It's free too. When activated, your Q will bypass ActivSync and it will be treated as a "jump drive". Active it, plug in to any computer, voila, jump drive. If you have a program running on your SD card, shut it down first. Can't handle internal and external access at the same time. Card Export II can, but as far as I an tell, only works on full PPC version.
