What are you guys talking about? You don't lose ANYTHING during a DSiWare transfer. You're supposed to restore your sysnand backup to your source console after the fact, and use the SD card from THAT console in the target. Literally everything but your saves copies, your games are still installed but need the tickets. Other than that the ONLY thing that's transferred that requires a reverse transfer after 7 days is your NNID if you have one. Otherwise, when you're done both of your systems will be identical as far CFW/software (unless you did it for a friend and uninstall stuff after the fact).
