Anyone know how to get miniDM onto a webOS device running 1.4.5?

I've read the wiki and rwhitby's posts here and I just haven't been able to figure out how to get the app installed into /. It might be a borked SDK install because it doesn't recognize the phone using novaterm/novacom on my win7 netbook. I did try reinstalling the SDK but right now I'm thinking maybe I'd be better off just updating it to one of the webOS 3 or 2.1 ones...

Anyway I'd appreciate any ideas or suggestions. I have a Pixi from Verizon, Sprint, and ATT and I'd like to compare signal strength with each provider in different areas. Pixi's seem perfect for the job.
