This is my first post, so, I wanted to thank everyone who contributes here. This entire website is a great source of information. That being said... I've had good luck with underclocking my rooted evo to save battery power. I am a somewhat experienced overclocker with other devices and I'd like to give it a try on my evo. Is there anyway to overclock without flashing a different kernal? Perhaps an app that I can play with? Thanks!
