Totally stock ROM and kernel other than being rooted. Running Juice Defender and have noticed very nice improvement in batter life. Still want more. Is there a free way to underclock the phone? I'm not looking for anything fancy, maybe two profiles: 384mhz with screen off and maybe 768mhz with screen on just to try it out for awhile. Overclock widget does not seem to work on my phone. Don't want to buy setCPU without trying first. Is there anything else simple and FREE out there?
