I have a few questions about rooting: 1) When you get a kernel that can overclock the CPU, does it also underclock/volt when the phone is idle in order to save battery? 2) If I wanted to remove the root, is there a way to get all of my apps back? Also, for contacts I assume I can just run backup assistant? 3)How much battery life improvement have you guys seen when rooted? 4) When official Froyo releases, would I just unroot and install that with no issues? Or will there be a problem? (I would leave the stock ROM if I root) 5) Does senseUI still work when rooted? 6) Can you use the Market and DL apps like normal when rooted, or do you need to find all the .apk's? Also, if I bought apps, then root, can I get them again for free? Thanks everyone!
