Ahhh, I see. Sounds like a winner.
Yeah, the speed increase will not be as significant as the Droid 1's was with Froyo (My droid more than doubled in speed with froyo). But it will be noticable. I know one guy on here who ran the old quadrant on his rooted Rezound with GB and ICS...went from 5400 to 6500. That about 20% I think.
