I have been reading and reading and I am still a bit confused on what I should do. All I really want to do is root my phone to allow free wifi tethering so I don't have to pay sprint another $30 a month, be able to control my CPU so I can try to help my battery a bit.... and whatever else I can do to help the battery. What is my best choice for rooting to get what I want? And also, do I need to install a ROM to get this. I know I need a wireless tether app for rooted phones, the setcpu app for my cpu control. Thanks in advance for the help!
