[T-Mobile myTouch 4G Slide] Mortico:
Ok, I don't know why or how this worked, but I plugged the phone back into the ubuntu box and ran JuopunutBear like 10 times. It failed several times, in different places, with different errors each time. So I just kept doing it over and over again until it finally worked!

I now have MikTouch 0.7 installed and working perfectly.

Below is a log of the funkiness I experienced with JuopunutBear in case anyone ever has a similar problem...
