I thought the 2nd Gen could be rooted with Z4 Root,
I have used z4root v1.3.0 on the 2nd Edition Gentouch78 (3.5mm jack, 3 axis-accelerometer, microphone, etc.) and it works fine. However, I haven't been able to get clockwork installed, and from what I've learned so far, you can't make a backup unless you do that first. I'm somewhat unwilling to try other things until I get clockwork installed.
