Im running the rooted Gingerbread on my RTD2 D2, and I couldnt be happier. The phone was instantly faster and smoother than before. Text messages go through faster, and oddly enough service seems more consistent.
I know Quadrant scores mean nothing really, but I enjoy running it to see if I've made improvments. I'm running Bloat Freezer, and Jrummy's Droid Overclock. With my CPU set at 1.35ghz, my best score on Quadrant was 2411. Naturally I'm not keeping it at that, but it was fun to experiment with.
