I have just successfully installed GOdroid on my enTourage eDGe, and it is awesome!

I was able to find the .apk file on my phone - G1 running CyanogenMod 5.0.7. Using the terminal application, I used the 'su' command to get root access, and using 'cd' and 'ls' to search through directories, I eventually found it in /sd-ext/app-private/ . Other places where .apk files exist include /sd-ext/app, /data/app, and /data/app-private. I copied the file to the sdcard by typing 'cp de.agrothe.go.apk /sdcard'. I then plugged the phone into my computer and got hold of the file. I emailed it to myself and installed it on the eDGe, it worked perfectly.
