Do not use this one.
I do have an .iso for the D2G in testing, I will keep you updated.
I originally built an .iso for the Droid X, it worked so well for so many people (42,000 downloads and counting) I decided to make versions for different devices. This .iso is for the D2, I will have another out for the D2G soon.

After a little googling it appears that you can use the D2 sbf but it will remove any of the R2D2 extras and it will just be a D2.
