I, like the rest of you have upgraded to .901 and overclocked. I set my CPU to 1.225Ghz (all the others would crash almost right away). I have noticed that the battery life has changed, almost as though I have a new extended battery. The over all speed of the phone is excellent. I was at 2100ish on quandrant and now I am at 2700ish and I just ran a CF-Bench and I am at 11675,3483,6759. Seems to be right on par with other phones running at the same specs.
I don't have a screen shot app installed, sorry no screenies.
