visit rumrunner.us and be sure to use device specific download for dlx (not the universal version).
to summarize options for dlx:
software version 1.xx - use facepalm
software version 2.xx - use moonshine (2.06 version of moonshine DOES work with 2.07 devices)
software version 3.xx - use rumrunner
how many times can we pwn the same device? time will tell.
